For the Ras fight, he has an Aoe knock back as well as freezes, which both slow down your movement. Try to fight in the corner to minimize the distance you have to close on him to get back into the fight or even better bring him to the stairwell outside of his room. Overall, sell FFXI Gil is pretty easy. The 3rd deed is sitting up close to Rass alter.
If good team tactics are not used there are several spots where a wipe could occur. The MOBs in Gnomeregan range from 28-32 elite and are generally found in groups of 3-5, with the occasional group of 6. As well as placed MOBs there are patrols that wander Gnomeregan that you need to be careful of. A fairly normal fight against 3 or 4 MOBs can quickly turn ugly if a patrol wanders by and you are unprepared. Most groups of 3-5 mobs have one high level 30-32 elite and several 28-30 non-elite mobs.
