Fix a prime $p\geq5$, an integer $N\geq1$ relatively prime to $p$, and an irreducible residual global Galois representation $\bar{r}: Gal_{\mathbb{Q}}\rightarrow GL_2(\mathbb{F}_p)$. In this paper, we utilize ghost series to study $p$-adic slopes of $\mathscr{L}$-invariants for $\bar{r}$-newforms. More precisely, under a locally reducible and strongly generic condition for $\bar{r}$: (1) we determine the slopes of $\mathscr{L}$-invariants associated to $\bar{r}$-newforms of weight $k$ and level $\Gamma_0(Np)$, with at most $O(log_pk)$ exceptions; (2) we establish the integrality of these slopes; (3) we prove an equidistribution property for these slopes as the weight $k$ tends to infinity, which confirms the equidistribution conjecture for $\mathscr{L}$-invariants proposed by Bergdall--Pollack recently.
