[10..] You start with 3 effect choices. Penalties:
Outsized. You have a Disadvantage for each Size your target is above your own Size. You can skip this Penalty if you choose 'Mount' as all your effect choices.
Choose from the following effects. You can choose each effect more than once:
Mount. Inflict a stack of Mounted where you are the source. All stacks Persist as long as this grapple does, then they are instantly cleared.
If the target Passes their Might or ArtificeSave, they can remove 2 of your chosen effects. The target can retry the Save at the end of each of their Turns. You can use a Reaction triggered by their Save to give the target a Disadvantage on the Save.
You can use this Ability again on an active target to add new effects to the grapple.
You are Blunted against all but the grapple target.
If the target of your grapple moves, you can use a Free Reaction to use Movement from your next Turn to move with them (preventing the end of the grapple.)
