Sacrifice is a frontal cone AoE.
As far as I am aware, Sacrifice is an circular AoE centred on your target. Evidenced today by me standing between two party members, one to my rear and one ahead of me, and curing myself hit both party members also. If it was a conal spell it would not affect the player behind me.
You do need to be facing the initial target of the spell however, so I agree with that.
Con AOE=circular small aoe on target
Thm AOE=HUGE very wide frontal cone with long distance AOE, cone will always start from yourself no metter who you chose to cast it on, making it much easier to simply stand far back and grab all party members with your heals, just make sure to tell the party to try to be infront of you, usually archers will be behind you so let them know to be in front, you might ask why. my personal opinion is that i rather, i get the aggro from behind if any instead of the archer which it would be troublesome if your healing forward and then archer gets hit behind you aswell.
Cure and Sacrifice will have theyr aoe accomodated according to weather you cast it with THM or CON. Edited, Oct 26th 2010 5:22pm by AggroDoctor
