Holy Hammer slayer with ward and infinite power charges

hey,

i've been meaning to play Holy Hammers this league. the skill gains more damage and extra hammers from expending power charges, and after exploring different ways to gain power charges, and i found the easiest possible generator i could imagine. Also ward stacking is great for both defence and offense.

1. perform an attack, celestial mathematics adds 8k flat cold and breaks ward
2. gain a power charge when ward breaks
3. also gain 10 flask charges for iron flask, multiply that up to 34 charges after flask charges gain from passive tree

rinse and repeat, the cycle works 100% of the time (except the rare occasion of flask siphoner getting a hit in, and reduced flask charge map mod). I can also tank very big hit damage thanks to the ward pool and instant ward recovery, also immortal call has like 90%+ uptime since cast on ward break grants a lot of cdr. thanks to all that, i can tank for example non-uber maven memory game and probably any hit damage in maps. for DoT, i have 50% reduced DoT taken from bloodline and 10% on pantheon, and life regen from overleech and vitality.
