Powder Gauge
Upon learning the action 
Royal Guard, a symbol will appear on the screen indicating when it is in effect. Royal Guard increases enmity gained from using other actions.
Upon learning the trait 
Cartridge Charge, the symbol which indicates the use of Royal Guard will change to also display the Powder Gauge.
The Powder Gauge displays the number of cartridges in your gunblade, which are acquired by using combo actions such as 
Solid Barrel and 
Demon Slaughter (acquired at level 40). Cartridges can then be used to execute several actions such as 
Burst Strike (acquired at level 30) and 
Gnashing Fang (acquired at level 60).
Players will have access to a maximum of 2 cartridges starting at level 30, which upgrades to 4 under the effect of 
Bloodfest (learned at level 80). The base number of cartridges then upgrades to 3 at level 88 and 6 under the effect of Bloodfest.
