Implosion
Enhances gravity in the target, dealing the highest spell damage in game Template:Skills
Comments
Single most powerful targeted damage spell in the entire game. Its damage scaling is vicious, and it can easily annihilate even the most resilient of enemies (excluding the higher-level Golems, even if you had Power 99 (*) and Orb of Silt)
(*) magic resistances: a Stone Golem has 50%, an Iron Golem has 75%, a Gold Golem has 85%, a Diamond Golem has 95%, a Crystal Dragon (also a crystal creature, not a golem) has 20%)). So the most damage resistant golem only takes 5% of the damage done. At Power level 99 and Expert Level Earth Magic (300 base damage not 100, same multiplicator (75 damage each power point),-25 mana spent not -30 mana points lost) the whole damage would be 7725 damage points (which would be health points worth a 25 creature stack of Titans with 300 hp each), 5% of which(7725*0,05 =386.25) would be 386.25, a stack of about 6 Diamond Golems.
With an Orb of Silt (+50% earth magic damage) the damage would be an new 100% damage of 11588 damage points, and the 5% effective golem damage would result in 578 damage points, shredding no less than and about 9 Diamond Golems with 60 health points each. Maybe diamond gathering via golem destruction is a spending a nice time relaxing from getting rid off 46 units of Golden Dragon creatures, and at the time one has reached 99 spell power points (via buildings like School of Magic (+1 to either Knowledge or Spell Points, once) or Library of Enlightenment (+2 to Attack/Defense/Spellpower/Knowledge each once after having visited the building and having reached Hero level 10 or by using Diplomacy to get in) the wasted mana on the spell may not be a scarce ressource in terms of knowledge points either.
Of course using Summon Earth Elemental (also a 5th level spell) would be a little bit brutish as it would work without having to cirumvent or consider magic resistance and the Orb of Silt would not be usable.
And then there are times when an Orb of Vulnerability becomes rather useful, so one would not have to consider magic resistance at all.
