Then how do Wizards re-memorize or switch around spells if they don't have their spell books with them?
Why are you adding more fiddly damage and bookkeeping and 'gritty realism' to the fighter, while hand-waving the same things away from the wizard?
That's what people forget about 3.x - by 'streamlining', they eliminated every balance mechanic that kept wizards in check. Oh, they automatically get the spells they want. Oh, changing spells around takes minutes. Oh, re-memorizing takes a few minutes. Oh, they can cast while a fighter is literally beating them with a hammer. Oh, when they take damage they can roll to keep the spell. Oh, they can take a feat to make that roll even easier.
This is more of the same. Oh, the fighter has to pay for equipment damage, the mage doesn't! Oh, the bread and butter possessions of a fighter that let them do what they do will eventually fail, the mage's doesn't! Fighter has to bookkeep his 'grim and gritty' rules, the mage's important thing is *out of harms way*!
IMO, my feedback is you need to balance this. Everything gets wear and tear for every character or just (like now) hand-wave it away. Otherwise, you're adding 'item dependency and cost' burden to classes that have the worst of it now.
Look, I'm a big fan of the fighters and martials in general. I even homebrewed a non-caster Intelligence class, the
Wanderer. I'm not saying that the spellbook can't be damaged. There is no "fiddly" damage to the Fighter's equipment: every character in the group take the same amount of equipment damage all the time.
I wasn't a player of 3.5, and keep playing AD&D until 5ed came out, precisely for the caster supremacy. But I see more broken potential in clerics and druids than wizards, because it's easy to "lock" them stealing/breaking their spellbooks, but the cleric or druid can cast all day in armor without flinching and using weapons to attack (CoDZilla was a thing back then, or so they say).
Of course, if the wizard don't take care about its spellbook it's going to break. I even fast ruled something for you (every fight the wizard don't obsesively protect its spellbook it's going to miss a spell), but then, this doesn't happen to clerics or druids, that ALSO has other tools to contribute to the party. Wizards are something of One-Trick ponies: they cast spells, or they suck. But they are affected sameway for broken staffs (that mostly are their arcane focus, so forget about material component spells) and clothes (the Bare-Assed Wizard is going to take a cold with that puny Constitution stat) and even weapons (they have to defend in some way in melee). Wizards aren't tier 1 this time, as they are very,
very vulnerable if they expose their spellbooks. I didn't "take away" fighter's potential (in fact, if you revise the file, you can see that heavy fighters are the less prone to damage their equipment, because the most durable items are the heavy armors and weapons).
In fact, I clearly see that you didn't understand how it works the document. EVERY character in a fight is on harm's way. EVERY character receive the SAME equipment damage at the SAME time, no matter if they are in the rear or in the front ranks, no matter if they only received 1 point or as much as 54 points of damage on the fight: no matter how dire the fight was, they only receive 1 equipment damage to every item. It's not fiddly at all! It's even a gross simplification that you could easily keep track of every session or every 2-3 sessions.
A normal staff is going to break fast, the wizard clothes are going to tatter and its magical ring is going to break. The cleric's holy shield is going to break. The rogue's rapier is going to break. If the wizard keeps its spellbook unprotected, is going to break. Otherwise, it don't. But if someone purposefully attacks a spellbook to break it, THERE ARE ALREADY RULES for it in the DMG. Also note that a spellbook is much more valuable and fragile than a sword. A fighter can carry two or three swords, and a backup dagger in its backpack. A wizard only has 1 spellbook with all their spells available. If it becomes wet, it's




ed. I even do such things.
I appreciate feedback, nevertheless. Just don't take me as a stupid, munchkinesque person who wants to




up the fighters. I've playtested this, and I can say that the fighter was the least affected overall, because of the duration of its equipment. The aaracockra (Stolasi, owl-folk in our world) cleric, with its holy symbol embedded on its shield, was the most affected one, as its armor was broken, its weapons were broken, and its spells were casted with less effectivity.
