Antemalge ideas are sooo good i like the expanding of vanilla terraria and adding bosses and ores that fit like a spider queen,vulture boss but mech brain is a must.
also this is a personal request from me but can you add a true Arkhalis ? you can just recolor it(or just copy past it) but increase the stats and plz keep the slashing animation cuz thats what makes it unique(if you did add it) also you can make a crimson/darkness/hellstone/ versions of it that requires the normal arkhalis to craft and if possible it would be cool if it would shoot stuff or Slashes! that would totally fix its short range problem( you can add many more true versions of weapons)
if you added true arkhalis that dose long range slashes plz name it ''True Arkhalis Unleashed'' which dose the cool slashes animation but also sends slashes flying since its Legendary Heroic Powers has been UNLEASHED!!
also suggestions:
1. Wider and farther slash arcs, because having some range is nice.
2. Every few slashes, it shoots out a beam in the shape of the slash arc (similar to other True weapons)
Unlike usual though, the beam would locomote in a similar manner to that of Demon Scythe, where it starts slow and rapidly speeds up(but not as slow till it speeds up plz).
3. It slashes even faster than the normal Arkhalis. Maybe even to Fetid Baghnakhs levels (not quite that fast, maybe a little slower)
4. Size modifiers work, and affect the slash arc size. if this is possible in the game engine.
5. It would be weaker than the other True weapons. Maybe at 60-70-80 damage per slash. Its speed and directional control are meant to compensate for that.
6. if you added long slashes you can make it not Auto Swing which will make you feel like your using strength and power to send that slash
the Joostmode
tModLoader - The JoostMod already dose justice to arkhalis by adding a nail which you get from breaking a non enchanted sword shrine(there are 2 sword shrines one that gives enchanted sword and arkhalis and the other gives nothin) and you can upgrade the nail to 105 damage and it shoots slashes and its EPIC.
i took those cool suggestions from:
PC - True Arkhalis [name subject to change]
if you wont/cant add true arkhalis its no problem but look into other weapons
