Sacrificial Over-Clock

You Sacrifice everything and Forcefully Over-Clock yourself for a Final Last Stand, your the last one standing, get up and Fight

Wait for it

Until your health is critical (Dm's/Gm's Discretion), you may not use this feat

Atomic Attrition

You make your final stand like it's your last day alive and your taking the enemy with you; You gain 1 extra attack, You regain Half of your health +5 (Rounded Up), and You Regain all spell slots 5th level and below for the duration

Last Member Standing

Don't let your allies Fall for nothing, while this feat is active you gain +1 to attack for every dead/Unconscious Party member, 

Rapid Integrity Loss

You Start to Visibly decay and crack from all of your Systems moving and calculating at hyper-speed while trying not to destroy yourself when fighting, From the moment you use this feat All Health lost is Permanent, You Spend all of your hit dice and take a Permanent -2 to all ability scores until a Long rest used to specifically to repair yourself; Even then, the after effects give you 3 exhaustion points, you take -2 to any saving throw and skill checks for the next full week for the time it takes to fine tune yourself back to normal

A Construct's Final Effort

If you fall in battle after using this feat you may make a Final Effort to Stand and fight, You regain 1 health to not fall unconscious; if you die after this, Only Divine intervention or a wish spell could bring you back, there are No Death Saving Throws after using this, This effect supersedes any Death ward effect (Death Ward=No Permanent Death) unless the Dm states otherwise, this can be used again with this feat after a long rest

Timed Decay

Your on a limit so make every second count, Forcefully Over-Clocking yourself caused massive damage to your systems causing you to only be able to stay conscious for 8 turns after activating this feat, afterwards you fall unconscious for one full day to reboot and repair yourself; You don't get the effect of Sentry's Rest and completely Shut-down
