Ice and Fire I just started a HC Zon and was planning on doing a magezon with ice and fire. 20 cold arrow, 20 freezing arrow, 20 immo, 20 fire arrow, 1 point in prereqs to get valk and the rest in exploding arrow. So my questions are: Kuko fires exploding arrows. Are those synergized by my fire arrow points? Is immoltion arrow a good/decent boss killer? With the 1 sec cast delay and 3 sec burn time that means there could be three arrows stacked burning at once IF the boss is standing still. If I use Kuko with the 50% pierce would it be truely worth the extra 4-5 points to get pierce skill to 49%? Any other concerns or comments?
