Congratulations, I realy, realy dislike DG on my iron. Did you solo cashed or floors from Ed in tokens? Thank you! I am eager to buy RuneScape gold finally be free! I trained it only doing solo floors which was rather painful, but there are a lot of boosts you should definitely take advantage of if possible. I dont think it could be feasable to token farm from 99-120 but I certainly think if you'd an extended dg daily every day and some token farming alongside that, it may be a feasible training technique. By level 120 though it's possible to get 2x the experience of a single hour of nominal farming in one large floor so it may not be worth continuing to nominal farm upon getting over 200k xp per floor.
When you do get max boosts xp becomes pretty fasy so that is a upside to practice with solo floors, but it gets really boring after a while especially if you do not enjoy dg already. I used ton't mind it from around 105-114 but I over it. It is luck but the xp aren't uncommon. Thieving locust would be the rarest but I discovered I dropped 1-4 per stock of cards (128k tokens) (although 4 is rare, I've received 6 in one inv before I think), preening ibis that you receive a bit more commonly at about 2-5 per inventory along with the cloning mosquito (double tokens) you may get from 2-7 per stock. Consistent Yak cards are far rarer when purchasing from the Bryll Thoksdottir. The most common cards I believe are the really shit ones, but it's pretty even for everybody except for yak.
For 10 dual xp cards that I think it would cost approximately 360k tokens/3 inventories, maybe 4 if you're unlucky. For 300-400k tokens, you will need only 4m xp and less if you are utilizing your dual loaf cards. That's easily accessible from doing your routine floors, though might be harder between 99-110 when you don't have as many floors unlocked. If it is not sufficient to upkeep tokens, you need to be able to supplement with nominal farming. A person pls tell me if this is scuffed maths however as far as my anecdotal experience goes, I found this sustainable. Luckily, I bought all useful unlocks by about 105 dg so needed a surplus of tokens going from then to 120, plus I did do daily gorago for your free card, for some of the time, utilizing the cards in my greatest potential floors.
Other cards I under-utilised which could help you enhance xp at lower levels were: Beguiling smoke devil - lets you open skill doors without meeting level requirements. Good if you aren't maxed but wish to push some dg levels for whatever reason. Whimsical Bunyip - a random card's effect is performed. In theory you can leave and re-enter dungeons activating this card and hoping for an xp boosting effect, but I am too lazy for this.
I completed most of my bearish unlocks (gold accumulator, elite dungeon chest, magical notepaper etc.. ) by degree 105ish so I could spend all of my tokens on gorago cards. I prioritised DG dailies and I was lucky to receive 114 prior to the daily nerf, nevertheless even after nerf I still did the long dailies. I'd always use my boss option to choose a non Blink supervisor to get a warped flooring and do a sizable other flooring. Once arch came out though I utilised the deathless relic so doing my floors became much faster as I could cheese blink without any danger for my xp.
I had daemonheim jobs 4 completed around level 99 and cheap OSRS gold used full outfit, party simulators. You can get around 1.3-5m at the top end with these cards. I would estimate if you use the avg solo exp speed at 120 is around 500k a hour!
