Legacy variants and mistakes in patch notes[]
There is a mistake in the patch notes for version 3.4.0. Existing copies of Wings of Entropy gained +7% spell block, while new ones dropped with +(6-7)%, not +7%. This means that there technically is a legacy variant discontinued in version 3.4.0, even though the change also affected existing copies.
There is also a mistake in the version 3.11.0 patch notes. The attack block chance was raised to +(8-12)%, not +(8-10)%.
