Blood Bond’s Summon Damage Absorption Effect
A highly useful skill for those who want to take summons with them, but useless otherwise and also takes time to obtain, Blood Bond allows your minions to help keep you alive longer by using them to offload some of the damage you take. Combined with the various damage reduction traits and strong armor, Blood Bond can help make for a very tanky build.
It is worth considering, some summons tend to last longer in combat than others, so summons like Seed Caller, might not help much since they get downed often by aoe attacks and getting in the way of melee strikes. Others like the Beckon skulls that fly through the air or the Tentacle Shot mod that creates whipping tentacle arms that often get ignored by enemies and have their own healing effect might be more useful.
How to Find the Blood Bond Trait
You can find Blood Bond using the Cryptolith Sigil on Cryptolith Towers that spawn in adventure mode once you have the sigil on you. To avoid covering all the steps in detail in two seperate places, you can see the specifics of how to get the sigil in the section ‘Finding Concentration’. Blood Bond is the second reward you will receive from the Cryptolith Towers.
Note: To consolidate this info without awkwardly placing the Cryptolith info in one trait’s guide over another, it will be getting it’s own event guide page soon, so consider the linked solution used here as temporary.
