Bandos's Book of War detail

Bandos's Book of War is a book held in the pocket slot, and is the God book aligned with Bandos. It can be purchased from Jossik for 5,000 coins at the lighthouse. Books of war must be made using all four torn Bandos pages which can be purchased from other players, obtained from treasure trails or by cremating a vyre corpse. Equipping a book of war allows the player to preach and perform ceremonies, such as blessing, last rites, and wedding rites, by operating it (none of which have any effect on the game itself, and are simply recited lines of text).

Lost books of war can be reclaimed by speaking to Jossik at the lighthouse, or from a player-owned house bookcase, complete with all pages that have been added, for 100,000 coins. However, the book will lose all its remaining charges, requiring the player to add additional pages in order to activate the passive effect.

After completion of One Piercing Note, if the book has all four pages, it can be used to create an illuminated book of war and unlock the god book off-hand override. This requires 60 Crafting and 60 Prayer, and grants 10,000 Prayer and 10,000 Crafting experience (for the first time only). The book of war is not consumed in the process.

Filling the Book of War with all pages currently costs 283,431 coins.

The book of war can be activated like scrimshaw to provide a passive combat effect. The book can be recharged with any Bandos page, giving 45 minutes of active time per page. This is shared, unchanged, with the illuminated book.

The passive has a 5% chance to activate per hit, and it has a 12 second cooldown once activated before it can activate again. When it activates, a shockwave hits the target, dealing 90-150% damage (PvP: 30-90%), reducing the target's Defence level by 5% + 5 and increasing its affinity values by 3 for 12 seconds.

This is based on General Graardor's hard mode ranged attack.

Debuff Mathematics

Revo/Manual combat has approximately 33 hits per minute, 33 chances to proc. The calculation for affinity usefulness can be calculated as follows - Combat can be split into two discrete phases:

  • 1. Affinity debuff not yet active and proc is possible
  • 2. Affinity debuff active, team is getting more damage in, proc is currently not possible.

Since passive has 5% chance to activate, each phase 1 will contain an average of 20 hits. Since the debuff is active for exactly 12 seconds, each phase 2 will last 12 seconds. Thus, together, a proc cycle will be a total of 20 hits debuff off, then 12 seconds debuff on. After it wears off the cycle repeats.

Cycles thus last an average of 48 seconds:

  • 36 seconds without the +3 affinity debuff
  • 12 seconds with the +3 affinity debuff.

An example utility function at 7 man Nex:Angel of Death, a pure DPS boss: Players with a standard Flanking 3 PF+vigour sunshine rotation and fully perked t90 gear can expect 180k dpm.

  • Inactive illuminated god book is flat +0.525% dpm.
  • Active book of Wisdom is +2.933%
  • Active book of Law +3.2% maximum (no movement)
  • Damage scrimshaw +5%
  • Superior Damage scrimshaw +6.66%
  • Bandos Book of War is +1.60% from direct proc damage, plus the damage boost for team. Assuming the team is under 94% hitchance for the entire kill, and 1 player has acitive Bandos book, average 25% of the kill will be spent with affinity debuff on (12 seconds per every 48 seconds). Assuming 7 man AOD, quake+gstaff, no SWH, that brings affinity from 59 to 62 while debuff is on, a +5.08% increase for all 7 players, or an effective +35.59% increase for the book contributor. Average of +8.8898% effective debuffer dpm per cycle. +8.8898%+1.60% = +10.4898%
  • Double Bandos Book of War: Since the debuff active does not stack with itself, phase 2 of the debuff cycle remains constant. Phase 1 time is cut in half. Thus, 2 books = 30 second cycles, 18 seconds debuff off, 12 seconds debuff on. The effective marginal gain of the second Bandos book is +5.338% effective debuffer dpm per cycle, a total of 5.338%+1.60%=+6.938%
  • Triple Bandos Book of War: the marginal gain falls off to +3.559% effective debuffer dpm per cycle, a total of 3.559%+1.60%=+5.159%

Note that the debuff does not have effect on minions or pillars, whereas damage scrimshaws do.

This means using a Bandos book is on par with best in slot pocket items, in situations like no-hammer, sub-94% hitchance 7 man AOD. 1 Bandos book is advised, ideally on base tank or 4ticker. All other team members should be on Superior Damage Scrimshaws.

Of course, if the team has a hammer, is using Maniacal auras, Nihils, Reaper necklaces, or other ways to boost hitchance, team hitchance becomes 100%. Thus, Bandos is no longer useful: utility falls to +1.60%. Bandos book is best used in large team, low-hitchance bosses.
