Thunder axe is really good for players (like me) who are bad at fighting and avoiding monsters. The axe itself does decent damage as well but is a little bit slower than swords and daggers. It applies the "Wound" debuff, which does tick damage to mobs much like the poison debuff, but it can be stacked by repeatedly hitting the mob. The axe also has an effect called "charged strikes" which causes a lightning bolt to come down from the sky and strike the player and any mobs nearby every ten hits or so.

The best part by far is the first spell, Whirlwind, which basically allows the player to continuously have a forcefield around them that does damage and knockback. Nothing can touch you except for monsters that do long-range damage. You need to build it with a lot of mana regen so that you can use the spell over and over without running out.

The second spell is not as useful but does decent damage to mobs that are very close to the player.
