Portrait
Strongheart
Strongheart is a fearless seeker of justice, risking his life to ensure that good triumphs over evil. He is thoughtful, kind, and seldom rash, yet never hesitant to punish those who spit in the face of law and order.
Changes
Strongheart is potentially a reworked champion in the Founders’ Day event and delayed until 8 July 2026.
Only abilities that have seen some changes will be displayed here - and be aware that there’s a lot of guesswork involved. Some abilities may not have names - some may have the wrong names - or specialisations might not be marked as such - etc.. Focus on the effect data itself.
Please do me a favour and don’t get all melodramatic about what you find here. I - and CNE - don’t appreciate it. These are spoilers and will almost certainly change before release - likely multiple times. That and we don’t have access to any upgrade data prior to release. Making assumptions on how the champions will turn out based on this information would be premature.
