"[05:29:00] [Client thread/ERROR] [FML]: Duplicate enchantment id! class ganymedes01.ganysend.enchantment.ImperviousnessEnchantment and class am2.enchantments.EnchantMagicResist Enchantment ID:100"

Enchantment Id crash. Uninstall Ars magica 2 and using configs fix the crash.

Yeah biome id conflicts are a pain. A small reminder to read the logs in the crash-logs folder. They contain some pretty usefull stuff.
