New? Your level is very low to compete in Trials. Not impossible, just very unlikely. Trials is level based. Means anyone can easily kill u faster even if u got the first shot off. I would suggest to hurry this iron banner to rank 5, use a emblem shader and mark for iron banner to increase the ranking buff as well as the buff for one mote. This will get u etheric light to reach 34 the quickest. After the iron banner, have a friend carry you through the first two parts of Crota normal to get better boots and gloves so u can wear an exotic helm. Good luck.
