Painkiller

Industrial Approach: 10th level Whenever you cast a tech power of 1st-level or higher, or deal damage using your Explosive Resilience feature, you can cause a friendly creature you can see within 30 feet to gain temporary hit points equal to half your berserker level + your Intelligence modifier. Additionally, while they have these temporary hit points, they have advantage on saving throws against effects that would cause them to be frightened.
