A small, lightweight, no recurring scripts, mod to add old open spells from TES! Not leveled list enabled.
There are three tiers (due to the clutter and redundancy of having all five) - Open Apprentice, Open Expert and Open Master. To obtain the spells, enter 'help "Spell Tome: Open"'. Three different entries should show up. Look at the item id, and enter 'player.additem <itemid> 1'. If you like you can deduct a fair amount of gold. All three spells are of the alteration school, and use green effects.

--Open Apprentice Lock--
Spellbook Value: 80 gold
Base Mana Cost: 64 mana

--Open Expert Lock--
Spellbook Value: 240 gold
Base Mana Cost: 137 mana

--Open Master Lock--
Spellbook Value: 800 gold
Base Mana Cost: 178 mana

All mana costs will be affected by alteration skill and perks and such. To use, simply charge the spell like normal, and fire it at a locked container or door. The lock must be of the appropriate difficulty. If the spell doesn't work, try and move closer and then wait a few seconds. It should work then.

Upon unlocking a container or door, an unlock sound will play, and if SKSE is installed, the notification "<container name, Iron Door e.g.> unlocked successfully!" will be displayed in the top left corner, without SKSE, the message will simply be "Unlocked successfully!". NOTE this mod does not require skse at all.
To install, copy contents into your data folder and then enable "OPENSPELLS.esp" in Skyrim.exe or a mod launcher of your choice.

Sorry that my textures are so low. The mod works in a way that no other open spell mod for Skyrim does, by utilising the under-appreciated "Equip Ability" function in the CK, allowing things to happen while the spell is equipped.
IT IS CLEAN, WORKS WITH ALL DLC AND MODS, AND WILL NOT BREAK SAVES OR ATTACH UNNECESSARY SCRIPTS!
Also available on SSE.

This mod was a resource specifically and originally created for Beyond Skyrim.
