Well, as I see it, the counter to Greater Pentagram is to send ranged attacks in to it, or lure someone out of it. You can also legitimately sprint through or burrow past one, as well as teleport in normally, though I think that last may be miswoven.

Unfortunately only Magi and Moondancers have ranged attacks, and those are easily stopped by a shield. Theoretically you can send in an angel, demon, or faes to break the shield then attack, but again, they can reshield. If Lusternia had stars tarot, that might be useful in that scenario.

Also, sprinting and burrowing do not get around greater pentagram as of the last time I tested it which was like 2 minutes prior to this post. The only skill that gets around greater pentagram currently is moonbeam and I imagine that was an oversight.

That last is an interesting point. I'm not a Tarot user, but isn't there a skill in it that allows you to toss tarots within the same area?

Being able to use a Greater Pentagram and a regular Pentagram together does seem very strong, though. Perhaps only being able to maintain one or the other would be better?

You can't sprint or burrow in to a Greater Pentagram, but you can go past one into the next room with them, was what I actually meant.

Just for the record, regular pentagram stops that and furthermore, let's assume they could fling cards in at you... what could they really do? With a monolith in the room, you could not be summoned out. They could hang, lovers, etc. you but really... that would just be a waste of cards. You could still heal back up, etc.

And regular pentagram also stops Raging Moon. Furthermore, a -lot- of major quests mobs are inside so it wouldn't even be possible.

Let's assume you could not use both. It would certainly be more fair than it is but would it still be fair in general? Hell no. You were standing at Rowena (indoors) for a long time with Greater Pentagram up. Even if you could not use normal pentagram, the only class that could bother you would be a Magi.

Um, Narsrim. Druids can also hit from another room away with their cudgel and sling. Surprising I know, but we actually have some active Hartstone members. Whoo. 

Making it wear off after a while wouldn't be much better, because you could just throw another one up immediately.  Maybe only make it usable  for one day a month, like how Autumn works?  You'd then at least have to rotate who's keeping up the pentagram.

Good trans ability and "this has the capability to completely screw game balance" are a bit different.

What if it worked like a prismatic barrier?  If you did something other than sit still and channel the pentagram, it'd break.  The problem with that would that it would then be very easy for a Mage/Druid/Rage coven to force you to shield/heal and therefore drop the barrier.  You could counter this by having healers there to keep you from dying, but Magnagora hasn't got healing, so they'd have a legitimate balance complaint.  The idea of only having one type of Pentragram up at a time would suffer from the same problem.

I reall like that idea. Just limiting the caster has to be inside the greater pentagram the whole time isn't a huge restriction since the fixes to it.
