Holistic Gatecrasher (V1.1)

A cosmic trouble-shooter, you specialise in being where you need to be when you need to be and making sure other people get where they are supposed to be going. Holistics the theory that all things are connected in a grand cosmic pattern. Everyone has a role in this grand pattern but for some this role is a little more active. A Holistic Gatecrasher is one of these leaves flowing in the stream guided from rock to rock, whirlpool to whirlpool, by the connections that make up our universe. A Holistic Gatecrasher finds their way into all sorts of strange situations and places dragged by their own curiosity and the whims of our interconnected universe. Diving between planes, escaping under extreme circumstances, and waking up at random in a bush on the opposite side of the plane - this is the life of a Holistic Gatecrasher.

Analyse Portal

3rd-level Gate crasher feature
You have a knack for detecting and studying portals. You can sense the presence of a portal or gate to another plane within 60 feet. In addition, if you study a portal or gate for 1 minute you learn how it functions – what plane it leads to, whether it requires a key or not, and whether it’s a one-way or two-way portal. If the portal requires a key, you learn what type of key would be required to open it.

Dimensional Slide

3rd-level Gatecrasher feature
There are secret pathways throughout the multiverse, and your experience with them allows you to tap into small cracks on any plane. You can use your Cunning Action feature to teleport up to 10 feet to an unoccupied space you can see.

Crack Portal

Crack Portal 9th-level Gatecrasher feature

Closed portals are a mere minor obstacle to you. You can spend a short rest to force open a portal without the need of the required key. The portal remains open for 1 minute but otherwise functions the same as the portal normally would. You can also try to force open a portal in a shorter time frame. You can spend an action to try and crack open a portal by making an Intelligence (Sleight of Hand) check. A typical portal is against DC 20, but especially complex or difficult portals may have higher DCs to crack (as determined by the DM). If you fail three times, the target portal shuts down and ceases to function for 1 day.

Magic Resistance

13th-level Gatecrasher feature

Your constant exposure to the pathways of the multiverse grants you advantage on saving throws against spells and magical effects.

Planar Dampening

17th-level Gatecrasher feature

You learn to not only sense the planar pathways around you, but to shut them down as well in a field around you. While this dampening field is active, you cannot be transported or teleported against your will while you are conscious, and creatures within 10 feet of you cannot teleport or travel the planes, including against their will through spells like banishment. You can suppress or resume this dampening field as a bonus action on your turn.
