I had an idea for a scenario and decided to post it. It's likely not a final version, but you get the idea. It's a relaxed and pretty random scenario, so it might not be a best fit for competitive play.
Scenario: Arcane Ruins
When making scenery, place three arcane ruins within 4 inches of the center line of the board and with at least 12 inches between the ruins. You can also deploy woods or buildings instead of ruins.
You control a arcane ruin if your model ends it activation within the scenery piece or within 2 inches of a building or a ruin that cannot be moved into. Model that flees, has lower cmd than 3, inert warjacks, wild beasts and incorporeal models cannot hold objectives. Model contests an objective, if it is within a forest or within 2 inches of a building or a ruin that cannot be moved into. If there is a enemy model contesting the objective, neither of you gain control. You remain in control of the point even if you move out of the scenery piece, until your opponent contests or captures it.
In the maintenance phase, after allocating focus, roll d3 for each objective you control. This is the amount of Arcane Rage tokens you can then allocate to units, warjacks/warbeasts, warcasters/warlocks or solos. No unit/model can have more than three arcane tokens. In the next turn, before allocating focus, remove every arcane rage token you allocated last turn. Unit gets a bonus depending of the number of tokens it has. Note that these are not cumulative. For example, if you allocate three tokens to a unit, it gets only the third bonus, not all of them.
1 token: 1+ str, mat, rat and ranged damage rolls. -1 def
2 tokens: 2+ str, mat, rat and ranged damage rolls. -1 def and -1 arm
3 tokens: 2+ str, mat, rat and ranged damage rolls, +1 spd, -2 def and -1 arm. Warjacks may charge for free and units get fearless. Warcasters get +2 rng for spells and may once in turn cast one spell for one less focus.
You can win this scenario by caster kill. Starting from the first players third turn, player can also win by controlling all of the objectives in the end of his turn.
