ARC Raiders Expedition 3: Complete Mat Guide & Farming Locations

Here’s a guide to completing all three steps of Expedition 3, including what materials you’ll need and the quickest ways to find them. If you’re pressed for time before the expedition starts, follow these instructions for a smooth completion.






![Analysis of the one-dimensional Heisenberg model reveals that symmetry-resolved entanglement, quantified through the scaling of charge variance [latex]\mathrm{Var}_{q}(L) = 0.0547(1)\ln L + 0.1334(8)[/latex] and number entropy [latex]S^{\mathrm{num}}(L) = 0.3483(9)\ln(\ln L) + 0.409(2)[/latex], exhibits logarithmic corrections indicative of quasi-long-range order, further confirmed by finite-size scaling of the subtracted Rényi entropy, which approaches a linear extrapolation to the thermodynamic limit as [latex]1/\ln L \to 0[/latex].](https://arxiv.org/html/2604.02307v1/x4.png)
