In Tibia version 7.4, Knights were not the overpowered juggernauts of later updates. There was no Exori (that came in 7.5), no Exeta Res (8.0), and no healing spells beyond Exura Ico (which was practically useless at low levels). You are a melee fighter in a world where Dragons one-shot you, Warlocks laugh at you, and PvP is decided by runes, not swords.
The year is 2004. There are no hotkeys, no offline training, and no wands for Paladins. The gameplay is raw, unforgiving, and entirely dependent on social interaction and mechanics that have long since been altered. For many, the "Old School" era—specifically version 7.4—represents the golden age of MMORPGs.
Good luck, warrior.
Knights regenerate 1 mana per 4 seconds (slow). You rely on (Creature product: Protection Charms, Life Crystals).
