Piloted boosting (someone logs into your account) carries the highest ban risk because developers detect login location and hardware changes. Duo queue is significantly safer since you control your own account with no sharing to detect. Self-play MMO carries are lowest risk, and coaching is ToS-compliant everywhere.

Most competitive games monitor login IPs, hardware IDs, and play pattern changes to detect piloted boosting. Boosting services mitigate this with VPN masking, but detection is improving - Riot's Vanguard and EA's anti-cheat track hardware-level identifiers that VPNs can't mask. Duo queue avoids this entirely since no one else accesses your account.

In competitive games (Valorant, LoL, Apex), matchmaking adjusts to your boosted rank, so you'll face harder opponents and gradually drop if your skill doesn't match. Some services offer short warranty periods with free re-boosts, but duo boosting or coaching that improves your own play is the only lasting solution. MMO carries (WoW raid gear, OSRS skill levels) are permanent.

In duo boosting, a high-skilled player queues into competitive matches alongside you - you play on your own account with no credentials shared. It's slower than piloted since your participation lowers the win rate, but it eliminates account-sharing detection and lets you keep playing during the boost.

A single-tier rank-up in LoL or Valorant runs $20-50, while climbing to top ranks (Challenger, Radiant) costs $200-500+. WoW Mythic raid carries range from $50-300. OSRS power leveling varies by skill - combat 99s cost $50-100 while slow skills like Runecrafting cost significantly more. Duo queue typically costs 30-50% more than piloted.

A 1-2 division climb in Valorant or LoL takes 1-3 days with piloted, longer with duo. Multi-tier climbs (Silver to Diamond) can take 5-10 days. WoW carries follow weekly reset schedules. OSRS skill training to 99 ranges from days (combat) to several weeks (Runecrafting, Agility). Most services provide estimated completion times at checkout.
