Absolutely. BTW, one of the spells I lack is mana spring... But I'm managing. Just did a few wicked battles. First Odin Alleim, Castle Bristol. Down, 0 losses. After that Peter Drayn, the armageddon guy with 7k peasants and demonesses. 0 losses, but it was a really tough fight. Then Zebat, or whatever his name was in the castle where Delaware is held. Down, 0 losses. And finally, Halt the giant. Down, 0 losses. All of them were listed invincible.
That was fun
Maybe I should have put a +50% XP scroll, but I usually keep those for level 40 upwards...
