**White attacks (melee_damage):** (768 + attack_power) / 14**Mangle: **melee_damage * 1.6 + 264

This formula is well-documented, and matches the in-game tooltip value. This formula gives Mangle an overall attack power scaling value of ~0.114 * AP.**Shred:** melee_damage * 2.25 + 405

This formula is also well-documented, and matches the in-game tooltip value. This formula gives Shred an overall attack power scaling value of ~0.161 * AP. *Note: Shred damage is affected by the Mangle debuff (x1.3) multiplier.***Rip (5 Combo point):** attack_power * 0.24 + 1553

This formula was determined via direct testing, and does not match the in-game tooltip value. At this time, I am unable to find any documentation from the game developers on this deviation/buff from the tooltip value. The correct 4 combo point formula is: attack_power * 0.24 + 1272. Rip also ticks six times over 12 seconds, so the value of each tick can be calculated by dividing the total damage by six.**Ferocious Bite:** attack_power * 0.25 + 941

This formula was determined via direct testing. In addition, extra energy consumed by Ferocious Bite converts to extra damage using this formula: extra_energy * 4.1.*Note: the above formulas represent the average damage of each attack. Melee, Mangle, Shred, and Ferocious Bite damage are actually represented in-game as a narrow range of values.*

**Mana:** 2370 + (intellect – 20) * 15 + 20

This formula was determined via direct testing.**Mana Regeneration (Every 5 seconds):** (0.001 + (spirit * Math.sqrt(intellect) * 0.009327)) * 4.43

This formula was estimated based on the developer-provided formula for mana regeneration, and reflects the slightly lower mana regeneration values observed while in cat form compared to caster form. At this time, I am unable to find any documentation from the game developers on the exact coefficient for cat form mana regeneration. *Note: this formula only applies to mana regeneration when not casting, and may not be relevant depending on the frequency of powershifting used.*

Currently, the dps model uses (raid) buffed cat form stats. I eventually plan to switch this over to using unbuffed caster form stats, however that will be a major undertaking (for those that remember the old WotLK model interface, it will need checkboxes for every possible buff).

The dps model as implemented incorporates a “perfect” attack cycle, including 100% Mangle debuff uptime, perfect energy usage and Rip uptime, and optimal powershifting usage. I’ll write more about powershifting at a later time, too. The dps model also currently outputs a lot more data than is strictly necessary within the model itself. For example, it will report the relative damage-per-energy of most cat form attacks, even though the model itself only uses Mangle, Shred, and Rip.

Anyway, more to come later, but I’m happy to be back! – Toskk
