It’s Bright Forest, so i guess it would kind of fit kingdom theme:
Badge: 40% boost spell damage in event + 50% chance to fairy fire random enemy on match 4/5
Medal: 160% spell boost in event + 100% chance to fairy fire random enemy on match 4/5
The extra effect might stay after event. So, you could switch one of year medals for having fairy fire on random enemy with match4/5. Would be usefull in pure faction attempts in delves etc.
Merlantis Bagde/Medal: 30% to submerge/100% on troop cast.
Urskaya: 30%/100% to gain Enrage on 1st troop.
Many kingdoms have their favorite “effect”, which could be adjusted to medals. Also medals that would give an extra trait to your troops could be fun:
Khaziel Badge: 10% chance to give Fortitude to random ally on start of battle. Medal: 50% chance to five Fortitude to random ally on start of battle.
Just some ideas…
