I have 300ce 100 mist energy and a mist tank. I currently have a boltbrand, dark thorn blade and other 3 star stuff.
What should i do. I have no trinket slots or weapon slots and have trinkets.[Health ones]
Should i get 2 trinket slots, 2 weapon slots or another 4 star weapon[Electron bomb] or a 4 star armor[mighty colbat armor] or save for a voltedge.
I also am a swordsman using fast swords is what i like. i want to be tier3. WHAT IS THE BEST CHOICE?
Although I'm always going on about it, some people have found my sword guide useful. It helps you select your piercing, elemental, and shadow sword (although you're well on your way --- you probably just want Nightblade/Acheron now). It also talks about armor and trinkets.
To address your specific questions: I do not recommend immediately getting two trinket slots or two weapon slots. A third weapon slot is nice, but not essential; a fourth is totally unnecessary. Trinkets are nice, but not as important as good weapons.
I recommend that you upgrade your weapons and armor to 4-star, then get a third weapon slot (unless you want it earlier, or don't want it yet), then upgrade your weapons and armor to 5-star, and then invest in offensive trinkets (particularly sword damage).
