When it comes to the mod loadout it is important to remember that a weapon should suit your playstyle.
Toxic and Heat are solid progenitor elements, honestly any element will do as this is best used as a high critical weapon. Keep in mind that Primed Cryo Rounds is a good element mod for damage.
The Kuva Hind has 3 firing moves that rotate with the alt-fire. By default it starts with burst fire mode. Pressing the alt-fire swaps the weapon to semi-auto, and once more to auto before looping back.
- Burst-fire mode: A balance between critical and status
- Semi-auto mode: Good critical chance at the cost of status chance.
- Full-auto mode: Good status chance at the cost of critical chance.
The [Kuva Hind] can take advantage of both critical and status builds as it can change modes. If you feel like you need a more status focused weapon, you can build it as a status weapon and set it to auto-fire to build up status stacks. Alternatively, if you need a sniper, but aren't a fan of scopes, you can build for critical chance and critical damage and land heavy headshots. However this weapon doesn't hit hard like a real sniper as it does not get the scoped damage multiplier. Mod as you see fit.
Happy Hunting.
