Ves always treated his DP like treasures. After a spate of troubles early in his career, Ves developed the habit of retaining a reserve of DP.
Points meant power. He could immediately spend his DP on a variety of benefits, from extra Skills to life-saving objects.
Ever since he'd been whisked away by an unknown alien gadget, Ves unconsciously treated his DP as a final failsafe. If he couldn't find a way to get back home, he'd spend his way out of this fix.
The more DP he saved up, the higher the odds of escaping this perilous situation. Many objects became available once he saved up more than 100,000 DP.
Right now, he temporarily shut that door by buying the Vulcaneye. While he could still come up with a couple of solutions with the 30,000 DP he had left, his options became a lot more limited.
"If nothing else, I can still wait until my points climb back up."
