For the final level in the game sin mark it is a good idea to have arrow splitting effect for your ice shot. If it seems too hard to just aim for the dragons head that's because there is an easier way! Ways to win: 1. shoot at the head (obviously the hardest way) 2. use splitting ice arrow on the head (next to the hardest but still quite effective) 3. use your splitting ice arrow at the stalactites handing from the ceiling this causes many stalactites to fall on the dragons head for massive damage) CAN ALSO BE DONE WITH ONE ARROW BUT ONLY ONE FALLS!
the last level is really easy all u have to do is get close to the dragon but not close enough that it hits u with the hammer or what ever its called once u find where that is u just start shooting arrows at it this takes a long time but its effective if u combine this with what sonic_feet said ull probably win even faster and its probably more effective
