I was trying to research spells and get him into battle fast so i only researched alt to 2 and ench to 1, i thought fatigue would not be an issue because of gems but i see now that it's not really viable without some reinvigoration.
I had earth 3 and water 1 because i was planning on researching iron skin next so i think i was only getting a +2 bonus with stoneskin, not really worth it.
About the attacks your probably right, i just saw that he was only attacking twice each round and assumed it wasn't working but i only had one battle then he got killed.
I didn't know about awe at level 10 dom, i had it at 8 anyway so it would have been well worth the extra 2 points.
I'll continue to try and achieve my goal of making a super tough wyrm
Thanks for the info guys, very helpful.
