How is no one running this rune? I just came back a few days ago (after a very long break from playing), and saw that it is now 20 nora when I was going through the list of SP runes to see what changed. This spell can literally win games for cheap. Use cases: Cage a unit by casting 2 of them. Separate an enemy unit from its allies so that they may not reinforce him (Nora Glades bottom font comes to mind). Continuously block passage of a single area indefinitely. It's especially broken on Shattered Peaks map as a stall tactic if you want to build up for mid-late game. Font rush and block an enemy from contesting a middle font, or even getting to their own font on some maps while you get yours. Trap an enemy ranged unit against one of your melee units (and a relic or another unit). An extremely funny tactic is to use the infinite blocking to prevent an opponent from attacking a relic you use to contest their font on certain maps. It needs a cost hike and/or needs to have the duration end on your opponents turn (increasing the duration to 5 turns might actually stop alot of the more abusive cases, assuming that it blocks itself from being cast).
