Iskenderun's Mystic Blast
|This spell throws a crackling sphere of destructive energy. The sphere will sometimes explode on impact, and the chance of it doing so is higher if the sphere has traveled less distance.|
Iskenderun's Mystic Blast (or IMB) is a level 4 Conjurations spell which strikes a single opponent with destructive energy, dealing moderate physical damage. It has good accuracy and excellent range, and there is a chance that the blast will explode upon striking its target, damaging nearby enemies in a starburst pattern as shown below:
X.X.X .XXX. XXOXX .XXX. X.X.X
The chance of this explosion occurring falls the farther away the target is from the caster:
Chance of explosion = 3/(2*(distance traveled)+2)
For examples, if the target is next to the caster, IMB have a chance of 3/4 to explode, and if the target is at a distance of 7 (the max range), the chance falls to 1/6.
Regardless of position, this explosion cannot injure the caster.
IMB is an excellent jack-of-all-trades combat spell. It is fairly cheap to cast, requires only a single skill to train, and can effectively damage any target regardless of resistances. Its explosion effect isn't reliable enough to make it a competitive area-of-effect spell, but all the same, it is still an admirable attack spell for the early- and mid-game (eg, frost giants, Ilsiuw). It suffers against durable, high AC opponents in the late game, however, but hopefully you'll gain access to Orb of Destruction or some high-level elemental spell long before you reach that point.
Prior to 0.11, IMB dealt more damage, but was unable to explode.
