I have tested this on the live server.Faust wrote:Best Mana Level for a Gain = ((100 - Meditation Skill) * 0.01 ) * Intelligence
Situation Based on hiicha's Post = ((100 - 79) * 0.01) * 40 <--- 8.4 or 8 mana if you lack the math skills.
Again, my post CLEARLY stated that it wasn't "impossible" at all but merely significantly harder with lower intelligence. Having higher intelligence is CLEARLY much quicker for gains since there are more possible chances of gaining in the skill. Please feel free to log onto the test center and run a Razor macro with a loop based on this formula and you will see for yourself.
I wouldn't suggest ever doing meditation with a locked low level meditation skill value though.
I started with 40 int/79 meditation and a little over 24 hours later I ended with 40 int/79 meditation. My macro was set to completely drain mana and then meditate ("If Int <= 0 then UseSkill: Meditation" if you lack the macro skills) and I never gained a single point (and I never once failed to meditate.) Featheon had the exact same results.
While the formula you presented suggests its possible, while improbable, to gain meditation, actual field testing proves you cannot gain past 79 meditation with only 40 int.
