As all players in this game know that 6 is really the minimum for effectiveness, but maxing it gives you godly stamina in Aika. 1in orb is nigh useless, maxing orb when you've already maxed fireball is pointless. Generally it is recommended you max hellfire for the reduction on cooldown, and the massive spike damage.
You can not to use Soul trap in a long time, but it has its uses. In arena you can try to tag an enemy with it so it will finish them later, During raids you could tag an enemy who ran too far out of his defense party so when he runs back he causes utter chaos, On bosses you can use it as bonus DPS. Maybe you have have heard people say soul trap does not take into account your full magic attack, OR your skill attack max score. Additionally the cooldown makes it somewhat unwieldy.
You should really pick up one point in it because its instant, low mana cost and has a short cooldown if you have no mirrored agony. This helps tremendously against divine ward, block and sidestep. You will not lose health if it is absorbed by divine ward block or sidestep, but a charge of their defense skill is still removed. Its also a decent finisher if used.

Maxing shackles is a bit of overkill, Rank 8 7 or 6 should give you plenty of time to down your target, especially if timed for the double effect. This one usues 6 manashield, so you will be squishier than the average WL who maxes shield. f you do decide you want maxed manashield, take inferno down to one, and flare down to 5. Or flare down to 1, inferno 5. Our Aika powerleveling is your best choice if you dont have time for your character.
