*v3.1*

- Introduction
- Mana regeneration
- Mana pool
- Haste rating
- Critical rating
- Summary

There are three areas which are affected by Critical Rating. There is the base 50% additional healing which results from a critical and then there is then one talent for each of the healing schools which is crit based. These are Divine Aegis for Discipline and Surge of Light for Holy.

Assumptions:

- Flash Heal is being spammed (1887 base heal, 80.86% co-efficient. 1.5s cast time)
- Discipline has 1950 spell power
- Holy has 2147 spell power
- 45.91 Crit Rating equals 1% Crit
- 167 Intellect equals 1% Crit – Due to Disciplines Mental Agility talent they only require 145 Intellect per 1% Crit
- 30% over-heal
- Divine Aegis is 70% consumed.
- Surge of Light procs are 70% consumed
- Inspiration prevents 5% damage (for 25% armour buff) and has a 40% uptime

## Base Critical value

Healing spells that critically hit heal the target for 150% of their normal healing value. To calculate the value of this additional healing we assume that the caster is using Flash Heal and use the attributes associated with that spell. To determine its value as MP5 we equate the total heal for the FH as MP5 based on the SP to MP5 ratio (0.6) and then calculate how much is additional healing is due to the critical. Over-healing is also taken into account.
