Benefits of Influence in KOTOR 2

[temps]

There are plenty of guides out there about how to get influence for each character, but even after searching a few minutes I didn't find what the BENEFITS are you get from influence for a few characters:
HK-47
Mandalore
Visas Marr
GOTO

What are the benefits of influence for those 4? Is it worth trying to get?

[cerberusiv]

HK-47 and Visas both teach you stuff that is useful but only if you have enough influence. Mandalore and G0-T0 I've never gotten far enough influencing them to find out.

[psychotron666]

You get abilities from them, I've done them all except goto, and I don't remember what they are. They're small buffs anyway, nothing groundbreaking from what I remember

[cerberusiv]

Visas teaches you the Force Sight power which lets you see others through walls and see their force alignment.

HK discusses how to kill jedi and you get buffs when fighting sith.

[Dethlane]

HK gives you bonuses when fighting jedi/sith.
Mandalore, IIRC, just talks about Revan and stuff.
Visas teaches you Force sight.
GOTO allows you to "deduce" his identity (never got it so dunno if it gives anything besides achievement or not).
So HK and Visas's ones are definitely worth to get, especially since influence with Visas can be maxed right after her encounter with dialogue, just be good to her and act jedi-like.

[cerberusiv]

Just don't max your influence with Visas and ignore Handmaiden. If you do then Handmaiden may refuse to talk to you. That makes it a little bit difficult to make Handmaiden a jedi.
