My Hero Roster has lots of Heroes which I most likely will never use. However I am not sure which ones I can savely get rid of. This is where I need your help:
Correct me, Challenge events seem to require you to stack a single element against the resisted damage to complete and get a good score. Therefore in the absence of a full set of rare, epic or legendary heroes of the same color you should keep duplicates and level up. Especially fast mana ones.
In terms of 3* the best elements for challenge events are blue/red/green mono teams. Tourneys vary by what elements and modifiers are allowed each tourney.
That said, for challenges I am keeping:
2 Gatos/Namahage/Rudolph/Brienne (1costume1 regular)
1 Ulmer, Valen Karil, Jahangir, Berden, Mnesseus, Isshtak. If I can snag 1 or 2 squire Wabbits they will be added to this. That covers those mono teams.
Aside from those, for tourneys and fillers to make different teams as well as complete a mono in all colors I am keeping:
2 Balthazar/Pixie
1 Tyrum, Chochin, Gill-Ra, Melia, Bane, Kailani, Gunnar, Hisan, Belith, Shrubbear, Hawkmoon and the 2 Nashgars I already maxed before I could replace them with Rudolph.
And just for sheer fun I am maxing a muggy team #DoYouEvenMuggyBro and 1 Vodnik/Bauchan just to see how those event 3s work.
4s and 5s my rule is simple, keep 2 dupes max for grade A heroes like Grimm/Pro, 1 dupe for other important ones like healers etc, and 5s 3 max regardless of who the hero is. Feed the rest.
I believe in just keeping 1 original of any unique hero you pull (never know when a buff/nerf will happen), but if you don’t want to do that feed all the other 3s.
As for 4s I simply keep 1 dupe of each healer, 2 dupes of specialty heroes. 5s I keep 3 max regardless of who the hero is. But seek other opinions on this Part.
If you want to rank in rare events, you will need to max some dupes/other heroes you don’t have yet, but you have a ranking blue mono team right now so that’s good. The others will at least get you set up with a couple mono teams and heroes in each element to compete and complete tourneys/events.
