What level, proficiency, tier?
Code:
select * from merc_spell_list_entries
where merc_spell_list_id = 3
and spell_type = 65536;
what does that return? that should list the 8 resurrect spells.
If it returns nothing, check that sql for those spells has been run. Also check spell_type in that same table for the datatype. I think at one time I had it as a tinyint, should be int.
Other than that, the corpse's owner should be in your group.
Do they heal at all, or just buff? What class are you?
