As soon as Ed touched the carvings on the wall and triggered assimilation, he was fed plenty of information.
[Assimilation is on cooldown]
It was all the information on the advanced lightning application. That was obviously to be expected. Still, describing it as nothing more than that was downplaying its effects. The advanced lighting application technique provided general information on how to take one's mana manipulation to the extreme. It was almost on an entirely different level.
The only potential problem Ed now faced was that Electricity was scarce in the orc plains. That was probably how the technique even came about. Any mage or warrior looking to benefit from the lightning element would find themselves inside a desert and they would need to make the most of any water they were to find while there.
'Scarcity can create necessity and necessity drives innovation' Such a saying seemed fitting for the particular situation.
