Slayer is a 4th level spell in the School of Fire Magic. It grants the target troop the fixed +8 attack bonus against the specified lvl 7 units, depending on the level of expertise in fire magic.

This spell is the strongest attack-increasing effect in game, except possibly Frenzy but also without its defensive drawback, granting +8 attack, but only against very specific 7th level units, and only ever to a single stack per cast.

Slayer depends on your enemies' army makeup - if you never encounter any valid targets, this spell becomes useless. On the other hand, if you regularly fight dragons or other "monstrous" level 7+ units, it can be a great damage buff, especially in endgame when direct damage spells are less effective than buffs/debuffs due to raw hit points/damage numbers. Against "valid" targets Slayer is slightly stronger than Bloodlust/Precision, as it grants +8 attack regardless of situation, but it is also more expensive and cannot affect more than 1 stack per cast. Being 4th level spell, unlike most buffs it can be cast on Green Dragons and Red Dragons. Fire Magic skill increases Slayer's potential, allowing it to affect wider pool of targets. Typically (without Fire Magic skill) it will only have an effect when fighting Dragons, Hydras and Behemoths. On Advanced level Angels and Devils are also included. Finally with Expert Fire Magic Giants/Titans also suffer increased attacker's strength. It is costly and inefficient spell, though, with relatively high mana cost and quite specialized effect - always targets 1 stack, only works vs specific targets, requires Fire Magic to achieve its full potential, and if you do have Expert Fire Magic chances are you prefer AoE Berserk anyway to use your enemies' own strength against them or Blinding them one by one.
