I dont know how it is for maggie but griffin harpooning the wraith doesnt actually impede it, unlike the other two monsters she can still use her traversal abilities(to full effect, not wasted like goliath/kraken) while harpooned.
Stage n3 it doesn’t, but Stage 1 you can’t warp away if Griffin is on the ground. You can warp ‘behind’ objects to break the tether, but Griffin can still hold a Stage 1 wraith without wraping going anywhere. We didn’t really test Stage 2.
Currently enduring a snorefest with a wraith now. Two domes and it just doesn’t want to fight. This is the shit that turns good reviews to average.
