	Cast/recast time formula: $Cast = \lfloor ( 100 - Haste ) * \lfloor ( 2 - f(Spell Speed) ) * Time \rfloor / 1000 \rfloor / 100$ Where Time can be 1500 for cast time or 2500 for recast time.

Use

Ruin deals damage to a single target with no additional effects, providing steady but unimpressive damage. When there are three or more enemies, Outburst or Art of War should be used instead. When there is nothing else appropriate to cast, Ruin is the spell to fall back on.

Ruin's cast time is slightly shorter than the 2.5 second global cooldown (GCD), allowing players a short window in which they can use off-global cooldown (oGCD) abilities such as Radiant Aegis or Whispering Dawn in between spellcasts.
