Branch affected by issue

base

Steps to reproduce

calculate DEF compared to https://wiki.ffo.jp/html/1704.html and https://www.bg-wiki.com/ffxi/Defense, note it's slightly off

Expected behavior

see https://www.bg-wiki.com/ffxi/Defense and https://wiki.ffo.jp/html/1704.html calculations work

Some effected areas:

server/src/map/entities/battleentity.cpp

Line 1107 in 4e93b67

m_modStat[Mod::DEF] -= m_mlvl + std::clamp(m_mlvl - 50, 0, 10);

server/src/map/entities/battleentity.cpp

Line 1021 in 4e93b67

int32 DEF = 8 + m_modStat[Mod::DEF] + VIT() / 2;
