I really like how this weapon plays but honestly it just feels really underwhelming compared to other weapons like the halberd.

Is this weapon just bad like that or do i just suck?? Is there some sort of strategy im missing out on that makes this weapon usable?

Are you seriously right now?;) Do you know how can be cool this weapon in good hands?

1) Cleave (Hit)
You can hit 3 targets with one very fast wide sword strike (Attack speed depends on correct timing + you can cancel the attack at any time)

4) Cleave (Roll)
The HOLD roll attack is uninterruptible and ignore the DEF stat (No matter how much DEF stat the enemy has 9999 or 9999999 or 99999999... just no matter... Cleave Roll ignore it) and at the moment of this attack you move and can attack 8 targets at once (Don't hold so much or... BAD Vertigo effect is comming for you)

3) Sword Parry (Block)
You can parry the hit and attack back (After Cleave Hit you can switch to block veryyyyy fast because the Cleave Hit can be cancelled and the shields can’t really do that because you need to wait for the animation of the attack and after use block)

4) Stab
Has the same 2 cells long attack as the Halberd (Deal more damage if the target is further away but... the attack cannot be cancelled same as Halberd) but the most interesting thing that you can make 2 combo hit (Cleave Hit + Stab) because the Cleave Hit can be cancelled. 

The False God Slayer has 3 problems:
- The Great Sword is slows your movement but you can switch to something else and your SPD will not be slow down (skill issue)
- The Great Sword requires at leats 20 COM stat so that you can do a good damage with it or you will have some problems in fight
- The Great Sword eats more STAmina than Halberd... So you will probably think that you need more CON stat to increase your STAmina... but a lot of CON stat doesn’t reeeally help you so much if you don't have at least 10 DEF stat and if you don't know how to play with False God Slayer (skill issue x2) and In general - the more damage you have the less stamina you will spend

Yes... Halberd on one side is even better than False God Slayer because of DPS and movement speed... except the fact that Halbert can't parry and can't attack through the DEF stat and Halbert is very easy to kill your companions due to the radius attack and high damage... but the greatest advantage that Halberd don't have that with False God Slayer you can literally stand close to the enemy and attack with this sword without taking a huge hit or injury (Parry + Cleave Hit) therefore most bosses or elite monster or highly protected enemies become harmless and the coolest thing is that you literally can switch to other attack or block or even any weapon at the moment of Cleave Hit.
