This spell bends space along a shroud covering your body, protecting you from some blows by redirecting their force to the air around you. Ranged attacks move too quickly to be diverted in this way. The shroud is highly unstable and may fall apart unexpectedly under stress.

Shroud of Golubria is a level 2 Charms/Translocations spell which causes some melee attacks which would normally hit you to miss. However, it may unravel after any strike, and will fade over time. Spell power increases the spell's duration, but has no impact on its success rate.

Shroud of Golubria has no effect on ranged attacks of any sort.

Duration: 7 + 2d(spell power) turns
Max Duration: 50 turns

Success Rate

First off, the Shroud only comes into play for melee attacks that you do not dodge or block. Of these attacks, there is a 33.3% chance that it will simply ignore the shroud and deal damage normally. Assuming that this event does not occur, damage is then calculated as normal (AC and GDR are applied) to determine whether the attack is deflected or if it causes the shroud to unravel.

Each attack that the shroud affects has a

Damage / (Damage + 10)

chance of causing the shroud to collapse and dealing damage as normal. If the shroud does not collapse, the attack is negated. This means that an attack that would deal 10 damage has equal odds of collapsing the shroud, being negated, or affecting you normally. Weaker attacks are more likely to be deflected, while stronger attacks are more likely to get through.

Strategy

Shroud of Golubria provides the caster with a surprising amount of safety for a level 2 spell. It works best when preventing large numbers of weak attacks, making it very effective in the early game or when the caster has significant AC and GDR. Even fragile characters can benefit from it, as it requires little MP to prepare before a fight and even an additional 10% chance of avoiding attacks can be useful. That being said, consider it a very worthwhile investment for otherwise magic-free, low-intelligence medium armour characters. Their low spell power won't hamper the spell too heavily, and these characters can also benefit from Apportation, a utility spell based off the same school of magic.
