Weapon Mod

they have Halves cast time 20% and halves skill recharge time 20% why not add a halves skill cost 20% ?

I like the idea of a weapon mod that has a 20% chance of reducing cost, but a few things must be placed in effect first: Firstly, the character must have enough energy to cast the spell. Otherwise you'd get people with 5 energy spamming a 10 energy skill untill it casts.

It's been suggested before, the difference between HSR and HCT of spells is that they are not energy efficient. Half skill recharge promotes spam with is bad for energy, while Half cast time also promotes spam, which is bad for energy. A Half energy cost doesnt promote spam (but unlike the other two, it relatively wouldn't affect spammability in a negative way), but is good for energy.

This mod would be overpowered. Half cast and half recharge are nice, but any caster willl tell you that the real control over casting speed is energy. Energy management plays a major role in any good caster's skill bar, and energy costs are calculated to balance the power of a skill with it's ability to be used. Interfering with that would seriously mess up the metagame.
