I've encountered this bug frequently with Vault Scribed Skill, Terrain, PVP, or PVE doesn't matter. I've fought at Mirrormoors, WB's, Dark Anchors, Delves, Group Dungeons, and Cyrodiil, just about everywhere it happens. Even when in an open field I can try to use Vault but it simply won't cast so I've resorted into not using the skill anymore till it's fixed. I tap the button like 3 or more times and it won't cast. I thought at first it was based off the Terrain but no, I've tested it with no edge or hill around and Vault still stalls on casting like there is an invisible cooldown on how many times we can cast it per hour.

I personally like the Vault and I find it useful to get out of AOE's along with dealing DMG to enemies or getting a heal off and debuff your opponents or buff yourself. But because it stalls way too frequently I'd say it's unusable for any and all content in ESO. So much to consider it not worth 50K gold in game, It's a waste to spend gold for a nearly unusable skill.

It's really annoying as on squishy builds it's perfect to get away from Maurauder heavy attacks. Unless when it doesn't fire! Now you're dead. Super inconsistent for an otherwise great skill. Please fix it's been a year

The skill doesn't have a dynamic range, it's a set static. What this means is you will always flip 15m back so if there is an obstacle there, such as a wall or drop-off it won't fire. So, it technically is consistent.

The skill would need to be changed to "up to 15m" and would require positioning calculations to ensure you don't go through a wall or over a cliff - which is no small feat.
