Stunned!?

[Snigel]

On live, getting interrupted was about position.

If you stood at position P0 = (x0,y0,z0) at time 0, for example in a corner to be able to find the exact location again, and started casting complete heal, you could run around while casting as long as you stood at (or close to) P0 at time T when the spell finishes and the spell would land.



that is,

if P0 = PT => spell success. Such that for 0 < t < T Pt was irrelevant. Meaning you could do whatever you wanted, except ducking, jumping or getting stunned in that time space.



This being the reason clerics were immortal in Bazaar arena PvP, where there existed corners to stand in. (Couldnt kill anything that had resists>0, but thats another discussion)
