Notes

• This spell is only accessible while under the effects of SCH's 1-hour Tabula Rasa.
  • Should Tabula Rasa wear off while you are casting this spell, you will get a message stating that you cannot cast this spell when the casting completes.
• To learn this spell, speak to Erlene in the Eldieme Necropolis (S) at (J-8) while on Scholar. (Your SCH must be level 5 or higher.)
• Does considerable initial damage (~Tier 5 spell), and gives a DoT that does about a fourth of the initial damage every tick. A well-geared, unresisted Kaustra can do well over 25,000 damage (initial plus damage over time).
  • Works with 3-second ticks, unlike Helices.
  • Unresisted duration is approximately 1 + (Dark Magic Skill)/11 ticks (or three times that in seconds).
• The base damage formula differs from regular magic damage calculations: floor(floor(0.067*Lv)*(37+floor(0.67*dINT)))
  • The base damage depends on the main level (Lv), not on the level difference.
  • 0.067*Lv is floored to one decimal digit, all other floors round down to the next integer.
  • dINT is caster's INT vs. target INT and caps at 300.
  • This formula is exact for most levels (including 99), but has some minor deviations at certain lower levels.
  • Other multipliers, such as darkness elemental potency and Magic Attack Bonus, are applied on top of the base damage normally.
  • This DoT effect caps at 24,999 damage per tick.
• This spell cannot be erased, but can be overwritten by (and overwrites) the effects of Embrava or removed (at least by monsters) with Exuviation.
• The effect of this spell will wear off if an affected mob goes passive.
