SpellBlade skill clarification (DM)

Looking at the adverseries, in particular the Spellblade under Mercenaries, they have an ability called Suppressing Blast
“mark a stress and target a group within far range. they must make an agility reaction roll or take 2D12 magic damage. Add a token to the action tracker for each target that marked HP on this attack”

What is confusing me is they have a range but not a radius, it just says “Group” to me that would be all PC in the far range distance. This makes the ability feel very overpowered for only a single stress.

Has anyone used this before or have suggestions or clarification on this ability.

From the compendium:

Targets & Groups
Rule
Often an effect asks you to choose a target within range. This means you choose a single creature to affect. When it makes sense in the story, you can ask the GM about instead targeting a single object in range, adjusting the effects as needed.

To affect a group of targets, these targets must be clumped together in an area within Very Close range of the others in that group. You can always ask the GM if something would be considered a “group of targets” before you make a move.

When you make an attack roll against more than one target or against a group, roll once and compare that total to each eligible target to determine which creatures you succeed against.

When your attack deals damage to more than one target, roll damage once and apply it to each target the attack succeeded against.
