Hi Can anyone help me with the rules for faction terrain and summoning please? I know that summoned units have to be >9" from the enemy when they are set up, but do they have to be 9" from faction terrain like the Idoneth Gloomtide Shipwreck or Nurgle Feculent Gnarlmaw? Also, is the answer the same for Dracothion's Tail reserve units, when they are set up on the table. Thank you.
no. unless your slann is inside the realm shaper you do not have to worry about it for summoning placement just how close they are to the summoner. the only rule is you can't drop them on top of the realm shaper as units can't end the movement phase on it
