Notes
- ↑ 1.0 1.1 1.2 The patch notes incorrectly stated that unique maps did not changed tier, however, they did. In 3.11, Cortex 's base tier is T9 and also have T11 and T14 variants. All variants have an area/monster level override, however. In 3.12 and 3.13, Cortex's map tiers are not changed. But other unique maps have changes in tiers.
- ↑ Contrary to the patch note that unique maps do not have monster level overrides anymore, all Synthesis Maps have introduced monster level overrides since version 3.9.0. In specific, Cortex can dropped with variable tiers since circa version 3.10.0.
