Pinpoint Weakness is a widely misunderstood skill in Aika. This does not only decrease your target's crit resist and dodge rate, it also let you use Terminate when your target hit 41% HP (aika gold). Great skill for dungeons, but not as useful outside it. Get it at your own risk.
Neutralizer, a basic skill, and many riflemen forget about this skill altogether. Neutralizer basically remove one buff from the target, prioritizes the first buff from the left. This have a lot of uses in PvP, and some in PvE. This skill is very nice against Osmanova in Lost Mines West, as it dispels his regeneration buff. In PvP, it essential against warlocks and their mana shield, and sometimes against hasted opponents, or those with angelic armor, but keep in mind that you can't choose which buff to debuff.

Headshot, the most controversial skill in your arsenal. a 5-second cast time skill that does ENORMOUS damage to your opponent. This WILL kill someone if it crits, if he doesn't have that many buffs on him, or a warlock with mana shield on. This is useless in PvE. Some people like using this to see large numbers pop up above people's head, but I think this is pretty useless. Large cast time, HUGE mana cost, and large cooldown make it crap in PvE, and it's only good for 1v1 PvP if you rifle smash or ambush the target, since everyone and their mom will wail on you if they see you stupid enough to cast this in plain sight.
