拉姆斯+升級荊棘之甲SBuild around the Upgrade: Thornmail hex. Use W's huge resists with Heartsteel and Warmog's for HP, then stack magic pen via Void Staff, Abyssal Mask, and forge. Once enemy MR is fully penetrated, Thornmail damage becomes near-true. Forge: magic pen > resists > HP. W also benefits from Jak'sho's % resist scaling. If enemies refuse to attack you, taunt with E to force the reflect.
拉姆斯+阿嬤的辣油AChili Oil for sustain — W instantly procs Chili Oil, stand and heal; if low, Q to back and heal during reset. Items: Bramble Vest first, then Sunfire; with extra AP go Radiant Echoes; third item Abyssal Mask; rest is tank stuff for the lineup. Easy early lead.
