Stop me if you've heard this one before here.
Just as the name implies, bombs which range and graphical placement would only be viewable to the party, and disregarded by enemies that casually avoid these (much like gremlins and PVP), inspired by mines placed in OCH.
I had thought starting them from the 2* blast bomb; weaker than the Deconstructor family, these do not cause either knockback or knockdown, only stagger. The bomb compensates this for both the linger and charge time the player is able to obtain via regular means.
2*: Blast Bomb > 3*: Hidden Mine > 4*: Stealth Mine > 5*: Proximity Mine
The player will initially begin charging the bomb, this charge time compared to that of DBB/Shard. When the bomb is placed, the radius of the bomb will be similar to the Shard bomb albeit the fuse time will be significantly shorter; completed, the bomb will "puff" as if it were a dud, and be hidden from any enemy sight, however the player will see it "tick", giving off the time remaining before it auto-detonates (much how shards do). If an enemy steps within the radius while active, the bomb will take approximately 1~1.5 seconds to detonate and cause damage to any nearby targets: the mine will linger at an estimate of 10 seconds, each * gaining an additional 2.5 seconds, capping at 15 seconds at the most. If the timer expires and no enemy has stepped on the radius, it will explode as normal.
This is just an idea that spouted. Any thoughts of improvements on this?
Gremlins don't avoid Bombs...
