[1.2.276] More rebalancing

If thunder charge stacks, then Paladins will be overpowered. Seriously. On holy weak/lit weak: 1.5 * 1.5 * 1.25 before defense. That is more than 1631.25% with the new blast. Over 1087.5% without any weakness.

With dual charge: 0.5 * 1.5 = 0.75, so a loss from the weakness. with another 1.25 boost, you get 93.75, so better off with lit alone.
