Recharging

[AnonymousHero]

I usually use the lazy version of your recharge strategy. That is, use up all charges of the entire stack, then cast a single recharge. If I get charges, I will use these first, if it goes boom, I will try to recharge again. This is significantly less tedious but of course the drawback is that you never have many charges available at once. This can actually help with charge drainers but means you may have to recharge during a fight. One of my priests killed the big M with wands of annihilation using that strategy, so I would say, the saved tedium is worthwhile.

This is the optimal strategy wrt. charges, AFAIK.

The recharging formula comes down to wanting to maximize

a constant - (number of current charges)/(size of stack).

If you split the stack, you have about the same chance of failure on each recharge, but more recharges; so it is indeed optimal to recharge a whole completely discharged stack.
