Conjurations attached to terrain...

[bigfatchef]

To replace a terrain fir another you have to pay
- the existing terrains casting cost
- the new terrains casting cost
- casting cost of all conjurations attached to this terrain. An example in RAW is whirlpool.

To understand it right: is any conjuration that targets a zone that is also targeted by an existing terrain attached to that terrain?

almost  correct. you would not have to pay for all conjurations attached to the zone, but conjurations attached to the terrain. whirlpool targets a terrain. dont think there are any other terrain targets at this time.

so pay for the terrain you are removing
pay for the new terrain
and at this time pay for a whirlpool if it is attached to the terrain being replaced.

Thanks for pointing that out. I believed whirlpool targets a zone. Then all makes sense!
