Recasting Life

Let's say that I (as a ritualist) cast the Life spirit. Then, I (or someone else on the team) casts another Life before the first one is dead (ignore that the recharge is 30 and it can only stay alive for 30 seconds). What happens? Does the first spirit die (because there can only be one copy) and do I gain the healing bonus because it died?

Yes, it does die and i would think you get the healing cause the first died.However these are again the things were Guildwars becomes a mistery on some things "end" or in this case spirit died will trigger and on some it wont.

Why dont you just test it out?

I guess the best way to answer that is just by testing it out. However, I don't have access to Guild Wars right now, so I was hoping someone already knew the answer.

The current life spirit dies, gives you health based on how long it was alive and new life spirit will raise. I used Life quite a lot in PvE when playing with Ritualist.

No need to test it, my Ritu was running this quite near the start of the game with a basic Rit Lord build without the Rit Lord (Quickening Weapon) and my Life spams killed eachotehr and chained the health bonus.
