So, hear me out.

Let Yoru have 2 Rift Tethers instead of 1, having all the same functionalities with the additional dynamic of expiry/decay timer for the Gatecrash ability to begin countdown if either of the rift tethers are placed/released.

The player can have both of the rift tethers placed/released at different locations but as soon as they cast the one of the 2 rift tethers, the other one vanishes and the restock timer begins.

Changes in restock time(If needed) can be tested and determined.

Casting Suggestion- instead pressing "E" (or enter your default signature ability button here)-

1. Press and hold "E"
2. LMB casts the rift tether you released first and RMB casts the rift tether you released second.
3. If only one rift tether is released/active, pressing "E" will do the job.
