Hello Will-o-Wisp
Core Rules known by all spirits, and the caster.
When the caster performs a significant action of a particular alignment, the spirit(s) that are in line with that alignment gain a boon point, and the opposing alignment(s) gains +1 Permanent max mana. At 10 max mana, new traits or boons will be unlocked for that spirit.
When spirits take actions on their own, these do not directly count towards 'significant actions' but may unlock or grant them unique boons. Enough uncontrolled actions can also grant unexpected benefits or penalties.
Important Information for you only
Due to actions during the prelude, you currently have the following stats.
Max Mana, refreshes daily: 8 Max mana
9 Boon points
Boons Specific for you
Deflection - 3pts
Abjuration Caster
You can use a reaction to parry an attack. Roll a con-check vs the attack roll, if you succeed, the attack misses. This has an obvious magical effect, unless you have some way of controlling the caster's body, or the deflection is hidden somehow.
You have a number of uses of this ability equal to your Con modifier, and refreshes on a long rest.
Arcane Ward-3pts
Abjuration Caster
You can weave magic around yourself for protection. When you cast an abjuration spell of 1st level or higher, you can simultaneously use a strand of the spell's magic to create a magical ward on yourself that lasts until you finish a long rest. The ward has hit points equal to twice your wizard level + your Intelligence modifier. Whenever you take damage, the ward takes the damage instead. If this damage reduces the ward to 0 hit points, you take any remaining damage.
While the ward has 0 hit points, it can't absorb damage, but its magic remains. Whenever you cast an abjuration spell of 1st level or higher, the ward regains a number of hit points equal to twice the level of the spell.
Once you create the ward, you can't create it again until you finish a long rest.
Universal Boons
Corporal Attunement - 3pts
You can add a bonus (or penalty) to any action, equal to the relevant stat-bonus. This can be done in addition to granting advantage(or disadvantage) to the roll if you have the skill as well.
Corporeal Control- 5pts
Requires Corporeal attunement.
Can take an action using the caster's body. In combat this means that the caster's body may be taking more actions than would normally be possible. The caster can prevent this, with no check. It can however be done without them noticing in some instances. Especially while sleeping.
Feats- 5pts
+1 Feat. Many stat-based requirements can be ignored, and you qualify if you or the mage combined meet the requirements, but many feats aren't as useful unless you also have at least Corporeal Attunement.
Stats-5pts
+2 to stat of your choice, or +1 to two stats of your choice.
Increased Level-5pts
Treat your level as two levels higher for any boon or spell effects that are based on level.
Mana Reserves-5pts
Gain 5 points of max Mana.
