The blood-dyed Seren godbow is a Seren godbow that has been dyed with a blood dye - it is otherwise the same as the undyed variant. This process is irreversible. It can be augmented with an augmentor to make the augmented Seren godbow (blood).

It has a special attack called Crystal Rain which costs 30% adrenaline and has a 30 second cooldown: five arrows are launched into the air in a 5x5 area centred randomly on any tile occupied by the player's target, with one arrow always in the centre. Each arrow does 50-200% ability damage if it hits, but if the target is hit multiple times, the maximum damage is reduced by 25% per arrow (larger targets are easier to hit multiple times).

The godbow has 60,000 charges of combat (a minimum of 10 hours) before degrading to a broken state. It can be recharged at a repair NPC for 4,800,000 coins, or less on an armour stand.

Making a blood-dyed Seren godbow costs 3,927,644,281 coins.

Seren godbow has a special attack called Crystal Rain which costs 30% adrenaline. Five arrows are launched into the air with the first arrow always landing and dealing damage one tick before the remaining arrows. If the attack is successful, there is a 30 second cooldown before it may be used again. If the attack misses, then the remaining four arrows will also miss, but no cooldown penalty is incurred, allowing the player to use the special attack again.

The first arrow always has an opportunity to land; the others may not have this opportunity as they need to land on a game square occupied by the target.

Arrow Ability Damage Range
1 80%-200%
2 80%-240%
3 80%-213%
4 80%-186%
5 80%-160%
All 5 arrows of Crystal Rain (special attack of Seren godbow) hitting Araxxi.

Using the special attack against an NPC which takes up a lot of game squares will increase the likelihood that multiple arrows will hit, potentially dealing extremely high damage. The determination of the number of hits a monster receives is described as follows. First, if the special attack hits, the first arrow will always hit. Then, the remaining four arrows will be determined. The centre of an NPC is chosen and the radius is calculated as the floor of half of the NPC size. A square within the radius from the centre of the NPC is chosen as the centre of the special attack. A 5x5 area centred at that square is where the remaining four arrows will be chosen. A random square is chosen from this area, and then random squares chosen, without duplicates, until there are four arrows, or when it fails to find a non-duplicate ten times. The number of squares chosen that also lie on the NPC squares are the number of arrows that hit. Targets that block the player from running through the game squares occupied by the target (such as Araxxi or Astellarn) always have the centre of the monster as the centre of the special attack. To add, there are targets such as Telos, the Warden on phase 5 and The Sanctum Guardian that are not classified as an NPC that blocks the player; instead, it is the environment (for these NPCs) that prevents the player from accessing the game squares occupied by the NPCs.

Interaction with multiple sources[edit source]

A demonstration of arrows 2 through 9 landing on a training dummy set to maximum hit mode. This was done by having each player cast Crystal Rain with the same setup of 1110 ability damage (using mechanised chinchompas) with no boosts, no perks, etc. on the same game tick. The remaining life points of the dummy is 86,680. This matches the expected damage by adding up the damage from arrows 2 through 9: 2664 + 2368 + 2072 + 1776 + 1480 + 1184 + 888 + 888 = 13,320. The damage from arrows 8 and 9, both 888, are not visible as there are a maximum of 6 hitsplats visible on a target at a time.

If a target receives multiple secondary arrows from Crystal Rain within 2 ticks of each other from multiple sources, then the arrows that land will continue with the pattern described by arrows 2 through 5. Sources in this context refers to arrows that are sourced by:

With this, the pattern continues on, up to arrow 8, where any secondary arrows that would land beyond this have the same damage range as arrow 8. Secondary arrows 6, 7, and 8 have the following pattern:

Arrow Ability Damage Range
6 80%-133%
7 80%-106%
8+ 80%-80%

Recommended bosses[edit source]

The Seren godbow is recommended for the following boss fights as its special attack can deal very high damage per use, depending on the size of the target. In general, it is recommended for bosses that occupy at least 3x3 game squares if casting this while using Ranged and for bosses that are at least 5x5 if casting this off-style with Melee or Magic (usually with the Ingenuity of the Humans).

The Seren godbow special attack does 50% more damage within Death's Swiftness.

Not recommended bosses[edit source]

The Seren godbow is not recommended for the following boss fights as its special attack does not deal high damage at all.

Damage analysis[edit source]

The probability of a certain number of arrows hitting given the monster size is shown in the table below.

The expected number of arrows are the average amount of arrows that land on a target of a specific size if repated many times.

Damage calculation[edit source]

Consider a 5x5 (size 5) NPC that is non-blocking. Finding the average damage done by the Seren godbow special attack can be done as follows. Note that the following assumptions will be made for this example:

To find the average damage done on a 5x5 in this example, the individual probabilities for the chance of each arrow to land are needed.

  • is the probability of arrows landing
  • is the average damage associated with arrows landing (in this example, as each arrow's damage is assumed to be uniform throughout their respective range, the average of the ability damage range is used for each arrow).

Interaction with the Ammunition slot[edit source]

Furthermore, the ammuntion slot is ignored for arrows 2 to 5. This means that if black stone arrows, dragonbane arrows, etc. are used, only the first arrow applies the effect from the ammunition slot and the damage and effect from arrows 2 to 5 are equivalent to having nothing in the ammuntion slot.

However, if the Seren godbow is stored inside the Essence of Finality amulet(or) and the Crystal Rain special attack is cast with a weapon able to make use of the enchanted bolt effects, all 5 arrows of Crystal Rain are affected.


Repair[edit | edit source]

The Seren godbow (blood) at most, costs 4,800,000 coins to repair completely. The repair cost is precisely calculated by the degradation percentage (i.e. with 75% charge remaining, a full repair would only cost 1,200,000 coins). It may be repaired through a variety of methods.

With an NPC[edit source]

These less preferred methods cost more as they do not consider one's Smithing level for a repair discount.

Alternate methods[edit source]

These preferred methods provide a repair cost discount of 0.5% per Smithing level (including boosts).

Notes[edit | edit source]

  1. ^ a b c d Approximations for non-Death's Swiftness columns include:
    For the Death's Swiftness column, values are obtained by taking the non-Death's Swiftness values and multiplying by 1.5. Damage caps are ignored for this part of the approximation. See calculator at top of section for more precise values.
  2. ^ Telos is 10x10 during phase 5.
  3. ^ Vorago is blocked on phases 5, 10 and 11 and during "The End" special attack.
  4. ^ Raksha is blocked on phase 4.
