At level 6 I summoned a 5th level skel and gave it a rusty scythe. This
helped it a lot letting it do around 16 damage a hit to orcs in cb. I was
able to easily take a orc that conned yellow to me and had bash(around 8 then
Id think). Also skeletons are not based on thee level a warrior are based at
they are based on the level of a creature so they actually have better stats
than an equivalent level warrior(without armor of course). This was stated in
an info by I think it was a guide at eqvault.com on magician's pets and this
was mentioned. So really dont complain about low level pet summonings
beecause they are actually better than you think.
There is also a bunch of info on neecro spells and pets and everworld.com and
I would recomend checking it out. It gives all specifics on when weapons
become useless and when skels pick up skills like bash and dual wield.
