Well this is pretty simple but for them noobs 1st try.

3 Tips for killing Andras:
1. Jump on the ledge and jump down to att him when his back is facing you (you looking at his back)
2: Assuming your a warrior just do jump and power strike or jump and attack.
why? cause then you wont get stunned at much
3: When Andras buff runs out, he'll buff again thats when you should spam attack him.

Andras does have a glove/shoe equip which is pretty good.

Andras glove stats: +2str (more or less) +8 hp (more or elss) i think 7 upgrade (more or less)

Andras shoes stats: (well i dont own one so i dunno ): )

These equips are untradable unless sisscors of karma is used
