For lvl 20 forge they seem very underwhelming. 400hp recovered is likely just setting heroes up to get killed again in short order. Surely its better to stock up and go equipped on ‘lesser’ items that might save the battle before you need resurrection.
Maybe it’s worth it if it adds a HoT, does the item need buffing, it seems strange that Alby skill outperforms the lvl 20 forge some of the time (%%%%) , and there is no hero with any skill even close to tornado or timestop.
Or is there some niche use where these are indispensible ( ehp bonus at end of event stage for a better score is all i can come up with)?
