2.16 THE CONSIDER COMMAND
Can you fight a mobile (npc) and survive? Use the CONSIDER command to help you make an educated guess! CONSIDER <player> will compare your might, which is a rough comparison of how many lessons you have spent in learning skills. CONSIDER <mobile> gives a general idea of the power of the mobile. For example, CONSIDER rat might say "A rat is quite powerful." NOTE: this is not how powerful the mobile is relative to you. This is on an absolute scale. The messages you may see when you type the consider command for a mobile, in order from strongest to weakest, are: almost glows with nearly god-like power does not even register your presence as a threat exudes an aura of overwhelming power has an air of extreme strength looks to be crushingly strong appears to be extraordinarily strong is quite powerful is not one to be trifled with seems strong and confident exudes a quiet confidence seems to be unafraid appears to lack strength does not look particularly dangerous is a humble-looking creature looks relatively helpless looks weak and feeble
