The first thing Nero did after entering the trench was not to explore up ahead, but was to spread his Frostburn to the walls, checking for any hidden cards. Just as he expected, several cards revealed themselves under the fury of his flames.
Eldrim cards themselves were not so durable, and could easily be destroyed - the very reason they were usually kept in grimoires when they weren't in use. Nero showed no restraint in freezing the cards and began running through the trench, freezing many traps along the way.
The trench, which was actually one of the most difficult obstacles of the course, was thus cleared easily by Nero with his team close behind. At the end of the course was a rope ladder which Nero climbed first, entering through a hole into a room.
