Krosmaster Arena - Version 4.x
Unfortunately, the Krosmaster licence is no longer maintained by its publisher Ankama...
But the French-speaking Community has kept improving the game by rebalancing all the existing profiles, adding brand-new profiles, clarifying the rules and making games more fun and balanced!
Before you start
What doesn't change
The principles of the game
The core rules (movement, combat, objectives) remain the ones you know.
Fun first
The spirit of the game is intact, but every character profile is now viable in a team!
The heart of version 4.x
What version 4.x has changed in depth
Based on the Krosmaster Arena 2.0 rules, version 4.x revisits several mechanics to balance the figurines and make games flow better.
Summons rethought
Each summon now has a Power level (1 to 3), and your team can only have 6 Power points of summons in play in total. Enough to keep games dynamic without the board overflowing with figurines.
Powers revised and clarified
Powers have been revised for more clarity or fun: some were removed, others changed, and new powers were added to enrich synergies.
Richer spell effects
New spell effects added to enrich synergies and strategies, with for example interactions with Demonic Rewards or the revamped Rebound mechanic.
Brand-new profiles
New, never-before-seen profiles added to complete the Krosmaster universe, with summon figurines already in your collections that now become playable as characters!
And much more...! Find the full details of the changes in the rule booklet and the updated profile cards.
