Incendiary Grenade
Weapon · WeaponThrowObject0★Mid-range throwable that bursts a few seconds after the throw and leaves the surrounding ground burning.
Incendiary Grenade is an early throwable: 8th of 11 by attack, so treat it as a stepping stone, at 750 against the 4,000 of Frag Grenade Mk2.
It feeds no other recipe, which makes it a terminal item: craft what you will actually carry and stop there.
Details
It weighs almost nothing and stacks to 9,999, so there is no reason not to carry a full stack.

Where to Find Incendiary Grenade
Incendiary Grenade shows up as world loot — junk hauls while fishing in the Mount Obsidian, usually 1–2 at a time.

Using Incendiary Grenade Well
The bench floor for this recipe is the plain Weapon Workbench — the first weapon station you ever build — and it never rises: a Weapon Assembly Line, a Weapon Assembly Line II, an Advanced Weapon Assembly Line and the Ancient Workbench all keep accepting it. Nothing about the level-31 tech gate implies a bench upgrade, so a single Weapon Workbench parked at an outpost is enough to restock in the field rather than carrying a stack out from your main base. What actually limits the throw count is Flame Organ; Gunpowder and Stone are both easy to keep deep.
Alternatives and Upgrades
Ice Grenade matches it exactly at 750 attack — those two differ in what they resist and what they weigh, not in raw attack, so picking between them is a swap rather than an upgrade. The next real step is Frag Grenade Mk2 at 4,000; below it is Shock Grenade at 750.
