3. Breakpoints
Faster Cast Rate (FCR):
75%, 125%. We use the 75% FCR breakpoint here. You sacrifice too much to get to 125% FCR and as mentioned it should only be considered vs a Barbarian
Faster Run Walk
145FRW (you attain this via Boots, Armor, Circlet and some charm investment)
Faster Hit Recovery
We are using Spirit Shield at all times - We do not invest in FHR.
Mana Pool
While Mana is not a breakpoint, with Mana Pots not allowed and when using Skillers, it can be tricky to manage your Mana.
Therefore Items, such as Circlet and Amulet require a high amount of Mana for the character to freely function. I strongly recommend 1000+ Mana (sacrifice damage if you have to).
This is also why wands and the runeword, White, are generally not considered optimal.
