Ryzom

1. So far on RoS I have only seen single creature combat (well except for that unfortunate Ragus train...ouch) are any groups of creatures in Ryzom aggro linked, ie if you attack one all will retaliate? Or can you in most cases get the attention of one creature (agressive or docile) and get it alone?

2. Related question, particularly for agressive creatures, is there pulling in Ryzom, with spell or ranged?

3. Is there healer aggro? I notice there is a fighter taunt skill.

I spent my formative years as a monk puller in EverQuest, so I'm always looking to see if there are similar "roles." I've missed Feign Death ever since.

1. Yes.
2. Yes, taunt is safer though.
3. Yes.

I'll add a bit more on #1:
Anything you wish, it's here with some species... aggro linked as you mentioned, social within own species, social with other species (except Homins *g*), not caring at all if the world collapses at the feet of the own trough... it's all there.
Some general rules to which there are many exceptions and some tactical prevention means, of course: boss guards are aggro linked, herbies are social and aggros don't care for anything else but what tastes good.

That way your #2 is considered an art by some... there's a lot a puller can do to kill his/her own group

That's all there to be discovered by you beyond Silan. Have fun

Pulling is an art. Just like all species eventually develop chess....and swedish meatballs.
