As the level cap increases we are having to give up more mastery levels
and even the whole tree in some cases. And it isn't gonna be any better
when 100 cap is out. So here is a quick guide to making speed drugs if
you have had to give up lightning for other trees and cannot afford to
buy the drugs.
Step 1: Grind until you get a sapphire tablet drop or buy one.
*Note: I think they are hard to buy, I don't see many for sale.Step 2: Make sure you have the correct elements (hover cursor over the tablet to show you.)
Step 3: Press "y" key to open alchemy window. Put the tablet in the "Material Process" slot. Then add all the required elements. Press Fuse.
Step 4: Say "BAM! Speed drug!"
There you go. That's how you get speed drugs without buying them from the NPC.
Diffrent level tablets give you diffrent speed drugs. Higher level tablet the faster
your speed drug will be. These are the levels and how effective each drugs will be:
Level 2 - 25% Increase
Level 5 - 50% Increase
Level 8 - 75% Increase
Hope this helped you out, Tell me if it did please
Credit to penfold for providing which levels give you what % of speed increase.
thank you
