+Buildings never are destroyed, just disabled for 15 seconds (unless sapped)
+Infinite sentry ammo
-Caps all buildings to level 2
-25% sentry firing speed

+ Hologram Mini-Sentries
+ Damage resistance from bullets and explosions
- Weak to fire and laser-based weapons

IDEA 2:
+ Creates a shield that blocks projectiles and bullets
+ Uses Metal
- Laser Weapons will pass right through the shield and deal mini-crits.

A sentry that doesn't die with infinite ammo would be really really OP. All an engie would have to do to push foreward is move up a sentry to a capture point and watch for spies. Even a level 2 sentry can clear a point if placed strategically, and a sentry that you can't take down would be able to deny entire sections of a map for entire rounds.

However, here's an idea that I had.

The Ethereal Extremity:
+Can deploy a decoy sentry at a cost of 50 metal
Decoy sentries can't fire, and have only 25 health
Decoy sentries mirror the upgrade progress of the actual sentry
Other buildings are unaffected.
-35% sentry knockback
-15% build rate

Honestly these stats don't work.... a level 2 sentry that can only be disabled for 15 seconds...... that would be so very OP even with the decreased firing speed.

Could use those LED sentries
+ Uses LED sentries that fires plasma
+ Sentries do more damage
+ Has more range
+ Melee causes a pulse that tosses enemies a short distance, minicrits/crits toss farther
- Sentry firerate -15%
-60% melee damage
-25% firerate/melee swing
-25 health when equiped

This could work in some ways but the problem is there are to many stats. valve items don't ever have that many stats

What if all the buildings could be created without using metal, but instead there was a timer for how long it could be deployed (lets say 30-60 seconds) and they have a cooldown time?

How about this maybe:

+You can cloak it
-It can't shoot while it's cloaked
-You can't repair it
-While cloaked, it takes +50% damage
-It's not upgradable

Or something like that, essentially a mini-sentry which is cloakable.

Or you build a generator thing that's worth 150 metal and the area its in lets you build holosentries that do reduced damage and you can build up to 3 little minisentries with less health. On the destrution of the generator, the minisentries have 10 seconds till they get destroyed

I can/could shorten the stats a bit.

Extremely OP.

+ 25% Damage
+ Enemy marked for death for 3 seconds (though cannot minicrit itself)
+ 30% Metal to Level (260 Metal)
- 30% Melee Range
- 50% Sentry Firing Speed (One Rocket per Second, read below)
No Critical Hits (No crits whatsoever)
Replaces Sentry with a Rocket Sentry

_____________________________________________________________________________

OPTIONAL: Level 3 will automatically try to destroy stickies with its barrel and prioritize them over players.

Other Thoughts:
Level 2 of rocket sentry could have two rockets per second and the same with Level 3 (the Level 1 looks a lot like the normal Level 1, but shoots rockets instead, and is slightly smaller)
Level 2 could look like the Level 1 but have another rocket slot above it (making it taller)
Level 3 could get wider with 3 rocket slots (tri-force design) with a 4-barrel minigun (obviously, since its 4 barrel, it will shoot slightly slower)
But the sentry will never fire all 3 rockets at once but rather in a clockwise pattern. (Level one is 1 RPS, Level 2 is 1.5 RPS, and Level 3 is 2 RPS (0.5-1sec reload speed for rockets)


Overall it doesn't seem too OP and it seems like it would be better as a defensive sentry (semi-efficient anti-sticky and can dish out a bit more damage than a normal sentry in the normal time span, but with less bullet damage (bullets take longer to kill than rockets)

Builds minisentries
+15% movement speed

More like where the GS gives you health, this would give you speed.
