Thaumic Fifimize
by PickLeaf
Thaumic Fifimize is a Forge addon for Thaumcraft 5 on Minecraft 1.8.9 that adds automation seals, fixes, renewable recipes and sapling boosts.
What it does
Thaumic Fifimize extends Thaumcraft 5 with tweaks aimed at automation and progression. Seals gain repairs such as correct interaction with Double Chests, a new Arcane Craft Seal handles arcane crafting, and a Control Seal can start Infusion Altar rituals. An Advanced Control Seal filters stored requests through a whitelist. The Seal Copier returns, letting players duplicate seals without repeating manual setup.
Other changes cover growth and resources. Silverwood Leaves can drop saplings at a configurable chance, and a Lamp Crystal speeds the growth of vis crystals. Some previously non-renewable items, including Netherrack and Shimmerleaf, gain renewable crafting paths. A harvesting shard stays with the wand so one is always kept. The mod is supplied with Forge only for 1.8.9, and it runs on client and server, so the server and every player need it.
Key features
Seal fixes and upgrades
Seals that failed to interact with Double Chests now work, so storage automation runs reliably.
Arcane Craft Seal
A new seal automates arcane crafting, reducing the manual input needed for complex recipes.
Infusion Altar control
A Control Seal can activate an Infusion Altar, and an Advanced Control Seal filters requests with a whitelist.
Silverwood sapling boost
Silverwood Leaves have a configurable chance to drop saplings, which helps forests grow without hoarding.
Renewable recipes
Items that were once non-renewable, such as Netherrack and Shimmerleaf, gain crafting paths that can be repeated.

Who it’s for: Thaumcraft 5 players on Minecraft 1.8.9 who build seal-based automation, and server owners who want fewer progression bottlenecks for their players.
