All recipes in the Invention System belong to a certain "Drop Pool". This is the only way to get each recipe without purchasing them from a Merit Vendor; though note that some recipes cannot be purchased at a Merit Vendor.
In the case of "Pool C" and "Pool D" recipes, these were originally awarded at the end of Task Forces, Strike Forces, and Trials. "Pool C" recipes were awarded for Task Forces, Strike Forces, and any hero-side Trials that were not Power Respecification Trials. "Pool D" recipes were awarded for Respec Trials and Hamidon Raids.
Pool A (Critters) Edit
Recipes from pool A are obtained by defeating enemies. Each time you receive a reward for defeating an enemy, the enemy defeated has a random chance of dropping one pool A recipe. (Giant Monsters and some Archvillains and Heroes are the exceptions to this rule.)
The level of a dropped pool A recipe is determined by the level of the critter that dropped it. (The exceptions are temporary power recipes are level 1 or level 10.) For example, if a level 34 enemy is defeated, any uncommon or rare recipe dropped will be level 34. A common recipe dropped by the same enemy would be either level 30 or 35.
Pool B (Missions) Edit
Recipes in pool B are awarded for completing missions. Every time you complete a mission, each team member who receives the mission completion bonus will have a random chance of obtaining a pool B recipe.
It appears that the recipe selection is based off of the mission's level, but the recipe's level is based off the character's level. Thus, a level 50 character exemplared to a level 15 mission may receive a drop from a level 10-20 pool. That drop will then attempt to be matched to the character's actual level; since the pool doesn't extend to 50, it maxes the recipe out at 20.
Pool C (Task Forces) Edit
- See also: Taskforce Random Recipe Roll
Now, random generation of Pool C recipes is only done as a Taskforce Random Recipe Roll at a Merit Vendor, at a cost of 20 Reward Merits per roll. Recipes are generated at your level, or at the maximum level possible for that recipe, whichever is lower. The level range selected in the right half of the Merit Vendor window (10-14, 15-19, etc.) will remove as possible selections recipes whose minimum is above the range or whose maximum is below the range. The level slider at the top of the Merit Window (1-50) only limits the ranges that are displayed, and does not otherwise affect the level of the recipe.
Pool D (Trials) Edit
- See also: Trial Random Recipe Roll
Now, random generation of Pool D recipes is only done as a Trial Random Recipe Roll at a Merit Vendor, at a cost of 30 Reward Merits per roll. Recipes are generated at your level, or at the maximum possible level for that recipe, whichever is lower. The level range selected in the right half of the Merit Vendor window (25-29, 30-34, etc.) will remove as possible selections recipes whose minimum is above the range or whose maximum is below the range. The level slider at the top of the Merit Window (1-50) only limits the ranges that are displayed, and does not otherwise affect the level of the recipe.
Pool E (Minions Only) Edit
- See also: Invention Made Costumes
Recipes in the pool E are similar to recipes in pool A in that they are rewarded for defeating enemies. Pool E recipes, however, are only awarded for defeating enemies ranked as Minions. It is possible for a single defeated minion to drop both a pool A and a pool E recipe.
All recipes in drop pool E are level 1, regardless of the level of minion defeated.
Special Means Edit
Recipes in this category are all awarded by means other than the normal pools.
Unknown Pool Edit
Occasionally, new Invention Recipes are introduced. They are placed in a special category until their drop pool is known.
Currently, there are no recipes in this category.
