# Talk:Critical hit

Some spading here. I believe that a Critical Hit with a spell multiplies the spell by 2, before bonuses are added on. That is to say, I think that it looks something like:

• (Crit*(spell_formula)+Bonus_Absolute_Spell_Damage)*(1 + Bonus_Percent_Spell_Damage).

Where Crit=1 for a non-critical strike, and Crit=2 for a critical strike.

To put some actual numbers to this. These tests are all using Conjure Relaxing Campfire. The damage formula for that spell is: (10-20) + (Myst/10), and it is an uncapped spell. I had 2969 Myst for these tests.

With +25% spell damage and +13 spell damage:

• If the absolute bonuses are included in the critical, the observed range for a critical strike would be: 2*(rand(10,20)+(2969/10)+13)*1.25 = 799-824
• If the absolute bonuses are not included in the critical, the observed range for a critical strike would be: (2*(rand(10,20)+(2969/20))+13)*1.25 = 783-808

I observed a 792 damage critical with +25% spell damage and +13 spell damage. Leading me to believe that the critical strike formula for spells does not include the bonuses in the critical hit, as reflected in the formula above. --MindlessGames 11:20, 15 November 2009 (UTC)

It appears per wiki data that clockwork crossbow may be the only weapon that will fire its on-critical effect from the offhand? I've definitely seen that from using the rusty speargun and the 7-inch discus; I'm leery of outright editing the actual page, as I am a weenie, but seems like it might be good info to add to the main article. Will do so in a few days once I get over the weenie part. --Laerjael 05:50, 10 February 2010 (UTC)

It looks like critical hits set monster defense to 0. I was attacking some shield-generator monsters dealing 20 damage per normal hit, 4-5k per crit.--BlanketThief 09:15, 1 May 2012 (CEST)

## 18 Nov 2012 changes

TPTMBG have refactored the mechanisms behind critical hits, as detailed in this forum thread. I'll see if I can hammer this page into shape. --Dentarthurdent 23:02, 18 November 2012 (CET)

...Oh right, that goes at Critical Hit Chance. And also it was two days ago. Nevermind. --Dentarthurdent 23:04, 18 November 2012 (CET)
