To everyone on the forums constantly saying, “just get Valiant”… I took your 'advice' and did it. Though, knowing my luck, a new progression will be announced any day now…

In all honesty, getting Paragon felt like a much harder grind. If you’re Paragon and feeling intimidated about pushing for Valiant (like I was), don’t be. It’s easier than it seems! I managed to gather enough resources to take two 7* champs to Rank 3 just by playing the game daily... no money spent on T4A or T6CC, no Necro runs etc. It took 24 days since beating Cerastes to gather the resources to R3 my 2nd 7*. (I already had one R3 7* before finishing 8.3) Tip: buy all the T4A you can from the Glory and Battlegrounds stores, which reset weekly. Pictured below is the moment I ranked up my second 7* to Rank 3! No regrets. Silk is an absolute beast and easily my favorite champ right now.
Huge shoutout to MCOC NOOB! I watched most of his “Easy Path” YouTube videos for 8.1, 8.2, and 8.3, and they helped a ton! Scytalis was a breeze... no boosts, no items. Big thanks to the forum for the Guillotine 2099 SP3 tip for the last 5% health! Bahamet was the most fun of the three corrupted bosses. I revived once but really enjoyed the ping-pong in the final phase. (I read about using the same Guillotine 2099 SP3 trick for the last 5% but skipped it.) Cerastes was tricky at first, despite many saying he was the easiest Act 8 boss. Took some time to find my rhythm, but once I did, it all clicked.
To anyone out there currently on the grind for Valiant: Good luck. You've got this!
