AOE Rain Spells' charges consumed by pets

[Throndor]

In velious, aoe rain spells such as tears of prexus did not attempt to land on Player Pets. Currently, they are landing on pets, in which the invalid target message is triggered, and 1 of the 4 charges is being spent on the attempted aoe of player pets. This needs to be fixed, player casted rains should only spend thier 4 charges on NPCs.

This means if i cast on 1 NPC, 3 waves of dmg land on that NPC.
If i cast on 2 NPCs, 2 waves of dmg land on that NPC (all three waves still tick to hit myself if im in range even tho the third tick is a "ghost tick" as far as the NPCs are concerned.
If i cast on 3 targets, i get 1 round of 3 hits, than 1 more hit on the closest mob to the center of origin from the second hit. (third wave ghost ticks)
If i cast on 4 targets, i get 1 round of 4 hits, then 2 ghost ticks.
