Terrorblade arcana worth it?

I'm buying the arcana either way but I just want to know if it is worth it in ur opinion

If you play a lot of the hero, yes, it is. Objectively it's one of if not the best arcana, what with the custom music and animations, especially the new death animation for whoever you kill. It also combines very well with his other items and sets, so there are no clipping issues there.

Yea the reason I was gonna buy it was cause it was by far the best arcana out of all of them and the death animation looks amazing and is the main reason I'm buying cause it's bad *** and the arcana itself also looks amazing when combined with gems especially the cursed black one

I also have 2 questions:is s and y better than manta when early fighting and is boots of travel better than treads because I usually go boots of t but it slows down my manta or s and y by a lot

Aquila > Yasha > BoTs > Manta > Skadi, always. Very inflexible item build. Treads instead of BoTs if:

a) They have a lot of nukes
and
b) You can't really split push into their team

or

c) You want to fight rather than rat

Ok thank u for the tips now I can wreak havoc on my opponents as they underestimate me and let me free farm

Listen dear young one
Get treads, get drums, farm Aquila and yasha and you are blody battle ready.

The traditional Luna/Gyro/any agi carry build of Aquila-treads-drums-yasha-dominator works wonders on an early fighting terrorblade. With good positioning, you can survive, get a good sunder off and even wreck towers!

This build although diverts a lot from the previous poster's build but it works. It just works.
You then progress into BKB, manta , butterfly and satanic. Get skadi late game when the fights drag and you need to kill fleeing foes.

As with Luna, never stop farming and use metamorphosis to take ancient stacks(stack at 00:53,tank yourself as you have lifesteal), push with wolf aura and take towers with illusion army and cut lanes when illusions are tanky(yeah you don't need radiance).

^Haven't tried it but that works too, Drums are pretty good if you want to fight.
