Re-reading the wheel of time series and tried to to replicate the warders that aes sedai have.
By weaving magical energies between caster and non-caster, both sides may share in a new power.
Prerequisite: ability to cast 2nd level spells
A caster may only bond with a creature who has no casting other ability other than those that are racial. If the bonded creature were to ever multi-class into a casting class the bond breaks.
Upon bonding the non-caster gains a +4 to 2 out of three physical scores of his choice. His attacks are now treated as magical.
A caster may do a few thing through the bond.
First any effects that the caster may experience can be shared up to half the amount to the non-caster. For example if the caster is healed for 10 hit point, he may share up to 5 pts with the non-caster. On the other hand if the caster is blinded for 5 rounds the caster may force up to 2 rounds of it onto the non-caster, these rounds do not need to be consecutive and may occur at any time before all rounds are consumed.
Also if the caster ever falls below 5 hp she may take up to 2hp/level from the non-caster as temporary hit points which the non-caster loses. These hit points remain with the caster for up to an hour at which point they revert back to the non-caster.
Lastly the caster may sacrifice a spell that she can cast a day and allow it to be cast by non-caster. The non-caster must have a Con modifier equal to the spell level +1. The non-caster chooses when he wants to use the spell. This may only be used once per day.
Magical Feedback: If either character falls unconscious the other must make a save, Fort for martial/Will for caster (DC 10 + ½ character level), If failed, character is stunned for 1 round and then staggered for 1d4 rounds afterwards. If character dies similar rolls (DC 10 + character level), if failed suffer ability drain (-2 to the original physical scores chosen when first bonded, or -2 to casting ability score).
Can sense each other’s emotions through the bond and because of it suffer a -5 to Bluff checks against each other.
To willingly break bond must spend an hour doing so and experience ability damage (-2 to scores as above).
