Well I just managed to nail the crazy bunny at level 12 using Magic Missile and kiting. Worth 3000XP! I haven't done my creature parts yet, I was just freelance exploring the Valley, and haven't done many quests yet. The jagon fight was not planned, I just entered the temple and had no save before hand.

I did not get Destruction as a skill, because until now, I saw more value in pumping up my base magic skills to up the4 damage. I was planning on dropping points in destruction once my skills are maxed. For magic, I was going for fireball, magic missile, and later firewall. I did not see much value in magic blast, and preferred to focus and max out a few skill lines.

Is rush attack worth upgrading?

Is it worth upgrading two weapon style?
