According to legend, when the Tuatha Dé Danann migrated to Ireland, they are said to have brought four magical instruments:

The Stone of Fál (Lia Fáil), which would cry out beneath the king who took the sovereignty of Ireland.

The Spear (sleg) of Lugh. No battle was ever sustained against it, or against the man who held it.

The Uscias Sword (claideb/claiomh solais) which belonged to Núada. No one ever escaped from it once it was drawn from its sheath, and no one could resist it. The sword is also described in the Tain as 'Nuadu's Cainnel' - a glowing bright torch.

The Cauldron (coire) of the Dagda. No company ever went away from it unsatisfied.
